c830473999 When creating a pthread in the suspended state their were two 
problems: (1) The wrong flag was being checked for in the attribute
	  (2) The pthread's state was not being set to indicate it was
	      suspended.

981f4968f0 It's unnecessary to lock the thread during creation. Simply extend 
the scope of the active thread list lock.

ca1c469cc7 Decouple the thread stack [de]allocating functions from the 'dead threads list' 
lock. It's not really necessary and we don't need the added complexity
or potential for deadlocks.

12c407a424 Return gracefully, rather than aborting, when the maximum concurrent 
threads per process has been reached. Return EAGAIN, as per spec.

4393f2c4ec Part of the last patch. 
Modify the thread creation and thread searching routine
to lock the thread lists with the new locks instead of GIANT_LOCK.

5ccf23715a Re-enable the garbage collector thread in anticipation of further 
locking work. I can't see anything obviously wrong with it (other than
the need to update the locking).

e7c9b7517b Fix build breakage (on ia64) caused by a missing file descriptor to 
_thread_printf(). Use STDERR_FILENO as the file descriptor.

55ad402a8f - Pass a ucontext_t to _set_curthread. If non-NULL the new thread is set 
as curthread in the new context, so that it will be set automatically when
  the thread is switched to.  This fixes a race where we'd run for a little
  while with curthread unset in _thread_start.

26f52e2f8b - Define curthread as _get_curthread() and remove all direct calls to 
_get_curthread().  This is similar to the kernel's curthread.  Doing
   this saves stack overhead and is more convenient to the programmer.
 - Pass the pointer to the newly created thread to _thread_init().
 - Remove _get_curthread_slow().

bb535300dd - Add libthr but don't hook it up to the regular build yet. This is an 
adaptation of libc_r for the thr system call interface.  This is beta
   quality code.
