 .SH DESCRIPTION
-.LP
 The \fBnanosleep()\fR and \fBthrd_sleep()\fR functions cause the current thread
 to be suspended from execution until either the time interval specified by the
 \fIrqtp\fR argument has elapsed or a signal is delivered to the calling thread
 and its action is to invoke a signal-catching function or to terminate the
 process. The suspension time may be longer than requested because the argument
