FWIW, here's a snip of the usleep(3) man page from FreeBSD 2.2.8-STABLE:

*Eight* system calls for each invocation, and a caveat that using select(2)
is even *less* compatible.  That's enough for me to forget about changing
from sleep(3), which *seems* to be working OK on:

 VMS, MVS (or is the EBCDIC port running on VM/CMS ?), Amiga, God knows
 how many flavors of UNIX, and perhaps some other OS's, as well (?).

Not merely to save a paltry 600 ms. of wait time ... no way ...!
