Hi Heinz,
The more conventional way to do this with pthreads is with a condition
variable, and the call
pthread_cond_timedwait. In this case, your thread wakes up when either
the condition is signalled or you reach a timeout. I'm not sure if this
is in RTL, but I think I recall that it is (check the docs).
