 .SS "Initialize"
-.sp
-.LP
 Condition variables and mutexes should be global. Condition variables that are
 allocated in writable memory can synchronize threads among processes if they
 are shared by the cooperating processes (see \fBmmap\fR(2)) and are initialized
 for this purpose.

 .SS "Condition Wait"
-.sp
-.LP
 The condition wait interface allows a thread to wait for a condition and
 atomically release the associated mutex that it needs to hold to check the
 condition. The thread waits for another thread to make the condition true and
 that thread's resulting call to signal and wakeup the waiting thread.

-.sp
-.LP
 If more than one thread is blocked on a condition variable, the order in which
 threads are unblocked is determined by the scheduling policy. When each thread,
 unblocked as a result of a \fBcond_signal()\fR or \fBcond_broadcast()\fR,
 returns from its call to \fBcond_wait()\fR or \fBcond_timedwait()\fR , the
 thread owns the mutex with which it called \fBcond_wait()\fR,
