particularly the "consume the signal you just sent" hang, and putting the wait queues in userspace. Do cancellation handling in pthread_cond_*wait(), pthread_join(), and sem_wait(). Add __ prefix to thr{sleep,wakeup,exit,sigdivert}() syscalls; add 'abort" argument to thrsleep to close cancellation race; make thr{sleep,wakeup} return errno values via *retval to avoid touching userspace errno.

2011-11-17Fix HISTORY:Ingo Schwarze
Mention the predecessor exec() in v1, and remove the bogus "appeared in 3BSD", just leave "execve() appeared in v7", because: (1) There is a direct line of inheritance from v7 (Bell, Jan 1979) via 32v (Bell, May 1979) to 3BSD (UCB, Feb 1980), and it goes without saying that children include code from their grandparents. (2) It is impossible that there was parallel development of execve() at Bell and UCB. The only UCB release before v7 was 1BSD (May 1978), and even 2BSD (May 1979) did not include any kernel parts but fully relied on the Bell v6 kernel. When Bell released 32v, the UCB did not even own a VAX, and Bill Joy was still are pure userland hacker. Only after the original UCBVAX arrived at Berkeley, Richard Fateman involved Domenico Ferrari who involved Ozalp Babaoglu who started kernel work at UCB, based on Bell 32v, later involving Bill Joy. (3) Genetic analysis of the source code confirms this. All kernel code involved is in sys1.c. Regarding this file, the first two UCB releases, VAX 3BSD (based on Bell 32v) and PDP-11 2.8BSD (Dec 1981, based on Bell v7) are more similar to their respective Bell parents than to each other. The Berkeley versions are cousins, not siblings: v7 -> 32v: 523 +71 -60 = 534 v7 -> 2.8: 523 +305 -24 = 804 32v -> 3: 534 +169 -110 = 593 3 -> 2.8: 593 +413 -202 = 804 References: http://oreilly.com/catalog/opensources/book/kirkmck.html http://minnie.tuhs.org/cgi-bin/utree.pl?file=32V http://minnie.tuhs.org/cgi-bin/utree.pl?file=V7/usr/sys/sys/sys1.c http://minnie.tuhs.org/cgi-bin/utree.pl?file=32V/usr/src/sys/sys/sys1.c http://minnie.tuhs.org/cgi-bin/utree.pl?file=3BSD/usr/src/sys/sys/sys1.c https://www.mckusick.com/csrg/ - /cdrom1/2.8/usr/kernel/sys/sys/sys1.c facts checked and ok sobrado@, style and formatting ok jmc@

2011-09-03knock out some useless Pp;Jason McIntyre
2011-09-03make -column lists pretty again;Jason McIntyre
specifically, rewrite them to permit some markup in the column headers, and use "Ta" instead of literal tabs; mandoc does not currently match groff 100%, but a mandoc fix may be some time off, and we've gone enough releases with poorly formatting column lists. in some cases i have rewritten the lists as -tag, where -column made little sense.
2011-08-19as with other list types, column lists generally do not need a Pp/-compactJason McIntyre
construct; this also sidesteps what seems to be a problem with mandoc, in that "-column -compact" seems to mess up the formatting. thus these pages should now have their lists formatted nicely (i.e. correctly aligned and with indent applied); as a side note, the fact that headers are not properly marked up is another issue which will be addressed separately (a mandoc fix is needed, i think). i have fudged a few of these to mark up properly, since the workaround does make sense for some pages. as another side note, i haven;t fixed man7, as i need to prepare a separate diff for kristaps and ingo.
