/*
Set mutex type to "fast" a.k.a "adaptive"
The mutex kind determines what happens if a thread attempts to lock
a mutex it already owns with pthread_mutex_lock(3). If the mutex
is of the ``fast'' kind, pthread_mutex_lock(3) simply suspends
the calling thread forever. If the mutex is of the ``error checking''
kind, pthread_mutex_lock(3) returns immediately with the error
code EDEADLK.
In this case the thread may steal the mutex from some other thread
that is waiting for the same mutex. This will save us some
context switches but may cause a thread to 'starve forever' while
waiting for the mutex (not likely if the code within the mutex is
short).
