Comment(by bonefish):
It's not particularly complex. See the attached patch for a possible
mutex_lock_with_timeout() implementation (utterly untested, though). It's
mostly identical to the mutex_lock() implementation, save for the use of
thread_block_with_timeout_locked() instead of thread_block_locked() and
the additional cleanup needed when the timeout does indeed occur. Since in
such a case it is also necessary to fix the mutex' count field (!KDEBUG),
the new field ignore_unlock_count had to be added to work around a race
condition with mutex_unlock().
