"When B<fork>(2) is called in a multithreaded process, only the calling "

"threads may have locked mutexes that are visible in the user-space memory "
"duplicated in the child. Such mutexes would never be unlocked, since the "
"threads that placed the locks are not duplicated in the child. The intent "
"of B<pthread_atfork>() was to provide a mechanism whereby the application "
"(or a library) could ensure that mutexes and other process and thread state "
"would be restored to a consistent state. In practice, this task is "
"generally too difficult to be practicable."
