The systems I checked have supported error-checked mutex type.
Linux 2.2 i386/alpha
PTHREAD_MUTEX_DEFAULT in Solaris is basically unspecified on recursive
locking. PTHREAD_MUTEX_NORMAL and PTHREAD_MUTEX_DEFAULT will dealock
on recursive locking. PTHREAD_MUTEX_ERRORCHECK is the checked mutex.
PTHREAD_MUTEX_RECURSIVE is the recursived one. PTHREAD_MUTEX_FAST_NP
one in Linux behaves the same as PTHREAD_MUTEX_NORMAL.
