The Ultrix sleep() is apparently based on or compatible with System V or
POSIX, while the SunOS sleep() is apparently based on BSD.  Both use
SIGALRM.  System V's does various pushups related to a previously
requested SIGALRM to behave essentially as if it did not use the signal.
This should be described in the sleep(3) manual entries.
