[PATCH] Fixed race in __pthread_mutex_init

[Thomas Pfaff]

__pthead_mutex_init had a race condition if the mutex is initialized with
PTHREAD_MUTEX_INITIALIZER (the mutex could be initialized by two threads
simultanously).
The patch wraps a mutex around mutex creation.

This is will be the last patch for a while. The feedback for the previous
ones was a little low, i do not know if no one (except Rob) is interested
in pthreads for cygwin or my patches are not welcome. I will wait for
comments now.

Regards,

Thomas

	* thread.cc (__pthread_mutex_init): Wrappped a mutex around mutex
	creation to protect against PTHREAD_MUTEX_INITIALIZER race.
