Use pid_t
Use vfork(), not fork() when sensible

- * It's sort of gross to call system commands in a subfork.  However
- * that's by far the easiest way.  These things are used only in
- * dired, so they are not performance-critical.  The cp program is
- * almost certainly faster at copying files than any stupid code that
- * we would write.  In fact there is no other way to do unlinkdir.
- * You don't want to do a simple unlink.  To do the whole thing in
- * a general way requires root, and rmdir is setuid.  We don't really
- * want microemacs to have to run setuid.  rename is easy to do with
- * unlink, link, unlink.  However that code will fail if the destination
- * is on a different file system.  mv will copy in that case.  It seems
- * easier to let mv worry about this stuff.
