LIBPTHREAD

  This is the pthread implementation of dietlibc.
  Written from scratch by Olaf Dreesen.

1. STATUS: near complete and should work (or not... I had a lot of heisen-bugs...)
	On non i386 archs the kernel header have major differences...
	NO workaround yet for this problems...

It's like linuxthreads a clone base thread implementation.

I have implemented a "Manager Thread" with all the pain it involves...
Nested thread creation is now working fine...


2. HOW-TO make this lib:

	it is a standard dietlibc helper lib...


3. NOTES

NON STANDARD SIGNAL HANDLING for the threads:

  SIGHUP	the targeted thread is canceled
	depends on the cancel type of the thread.

	ASYNCHRONOUS: the signal handler will KILL the thread immediately.

	DEFERRED: the signal handler mark its thread as canceled.
		(only for the sig-handler to do some sane stuff...)

  SIGTERM	the thread is KILLED
	if the thread signaled is the main thread, then ALL child-threads
	will get a SIGHUP and after some micros a SIGTERM....
