This is a list of things that still need to be done:
* Add thread stuff to the other archs in libc/arch/; ie change
some usages of ENTRY to SYSENTRY in some .S files and add
the new macros to their SYS.h.
* Find a better way of doing the _sys_aliases stuff; ideally by
using the linker. jmp's and branches (current implementation) are ugly, but
I don't want to have to hack ../libc/sys/Makefile.inc just to
partition the syscalls into wrapped and non-wrapped. The `.set'
assembler directive just doesn't work as I thought it would.
* Test that thread_init is automatically called on every arch, regardless
of whether the exe is statically linked or not.
* Alter the objective-C compiler to see if it can use threads.
It looks like the easy way is to just define CC='cc -pthread'.
* Find all the static buffers in libc and make them per-thread. This
is not absolutely necessary but incurs no penalty for single-threaded
operation, and makes life easier & safer for when threads are used.
On the other hand, it adds a bit more code bloat when you use threads
and makes openbsd programs non-portable to other OSs with less-nicer
libraries. If we do the bare posix minimum, we promote portable code.
* Look into how netbsd are going with their kernel threads
* Look into how asynchronous I/O can help us. In particular, the
(unimplemented) aio*() functions.
* Update the libc manual pages to describe the posix re-entrant functions.
Although this is actually trivial to do, I have to decide on a
consistent way of adding them - maybe `.Sh THREAD-SAFE FUNCTIONS' ?
Should look into standards to see what they suggest/did..
May also need to document "This is not thread-safe" for some library
functions (yet to be identified).
* Find out where freebsd/netbsd use pread() and pwrite().. i think
its in the database routines mostly. We will need to rip their code.
* Figure out what to do with the configuration system variables (_SC_*)
that are defined by POSIX 1003.1c
