No, cancelling the sleep works (at least for Unix). Isn't cancelling

Anyway, I've changed it, removing the ~2000s limit is a good point.

Won't this result in a call to pg_sleep with a long sleep time ending up
sleeping noticeably longer than requested?
Looks like it to me.
Instead of using a counter it might be better to set a target end time
and check that against the value returned from time() or gettimeofday().
