/ This file contains the c interface to the sleep (II) system call.
/ The icmp daemon uses the system sleep call rather than the standard
/ C library sleep (sleep (III)) because there is a critical race in
/ the C library implementation which could result in the process
/ pausing forever.  This is a horrible bug in the UNIX process
/ control mechanism.
