If the signal causes program termination, @code{pause} doesn't return
(obviously).
+This function is a cancelation point in multi-threaded programs. This
+is a problem if the thread allocates some resources (like memory, file
+descriptors, semaphores or whatever) at the time @code{pause} is
+called. If the thread gets canceled these resources stay allocated
+until the program ends. To avoid this calls to @code{pause} should be
+protected using cancelation handlers.

The @code{pause} function is declared in @file{unistd.h}.
