sleep will will make things more interruptible. Even a sleep 1. So, it simply means you could lose one second at most vs not having it, and you can interrupt it (if that's important to you). Makes it more multiprocess friendly.

SLEEP(3)						     Linux Programmer's Manual							  SLEEP(3)

NAME
sleep - sleep for the specified number of seconds SYNOPSIS
#include <unistd.h> unsigned int sleep(unsigned int seconds); DESCRIPTION
sleep() makes the calling thread sleep until seconds seconds have elapsed or a signal arrives which is not ignored. RETURN VALUE
Zero if the requested time has elapsed, or the number of seconds left to sleep, if the call was interrupted by a signal handler. CONFORMING TO
POSIX.1-2001. BUGS
sleep() may be implemented using SIGALRM; mixing calls to alarm(2) and sleep() is a bad idea. Using longjmp(3) from a signal handler or modifying the handling of SIGALRM while sleeping will cause undefined results. SEE ALSO
alarm(2), nanosleep(2), signal(2), signal(7) COLOPHON
