sleep() fails because it is being interrupted by the signals caused by
manual syncing.  The only way I can think of to get around this is to
use select(2) or giiEventSelect(), but getting interrupted 20 times per
second doesn't help you much, does it? :(

(It shouldn't happen on the XLIB target though...)

If you really want to sleep, the best way is to simply turn off SYNC
mode (use ggiSetFlags(3)).
