2aa9de1f77 o Implement pthread_mutex_timedlock(), which does not block indefinitely on 
a mutex locked by another thread.
o document it: pthread_mutex_timedlock(3)

2b33fc6470 Make it possible for the library to specify a timeout value when 
waiting on a locked mutex. This involves passing a struct timespec
from the pthread mutex locking interfaces all the way down to the
function that suspends the thread until the mutex is released.
The timeout is assumed to be an absolute time (i.e. not relative to
the current time).

Also, in _thread_suspend() make the passed in timespec const.

f2c3dd08ec Preparations to make libthr work in multi-threaded fork()ing applications. 
o Remove some code duplication between _thread_init(), which is run once
  to initialize libthr and the intitial thread, and pthread_create(), which
  initializes newly created threads, into a new function called from both
  places: init_td_common()
o Move initialization of certain parts of libthr into a separate
  function. These include:
	- Active threads list and it's lock
	- Dead threads list and it's lock & condition variable
	- Naming and insertion of the initial thread into the
	  active threads list.

ó++ ABI document at http://www.codesourcery.com/cxx-abi/abi.html#dso-dtor

The ABI was initially defined for ia64, but GCC3 and Intel compilers
have adopted it on other platforms.

2543fd4700 Comment out most of pthread_setschedparam. Pthread priorities didn't 
work before anyways, and I didn't want to fix broken code I had no
way of testing. It was necessary however, in order to get rid of GIANT_LOCK.
Pthread priorities will have to wait a little longer to get fixed.

33b7c0d94c Fix a strict aliasing issue. Also remove an unnecessary pam_get_item() 
call (pam_get_authtok() will return the previous token if try_first_pass
or use_first_pass is specified).  Incidentally fix an ugly bug where the
buffer holding the prompt was freed immediately before use, instead of
after.

6ed6ccb310 accept() returns a file descriptor when it succeeds which is very 
likely to be non-zero.  When leaving the cancellation point, check
the return value against -1 to see if cancellation should be
checked.  While I'm here, make the same change to connect() just
to be consisitent.
