Can anybody shed a light on this? // 23 May 01 WEKEMPF Removed "duration" timed_waits, as they are too // difficult to use with spurious wakeups? I need relative time waits and this comment made me wary. Thanks for your time, Georgi

I need relative time waits and this comment made me wary.
Since condition waits should always be done in a while loop, it's too easy to miss that the relative timeout needs to be recomputed on each iteration. Absolute timeouts don't have this problem.
