There is no equivalent of "wait forever" though.
Thanks a lot! Setting it sufficiently high gives me exactly what I need. One suggestion for the docs: I actually had (admittedly very quickly) tried CheckSynchronize with a timeout before. However, the procedure outclevered me, since for the test I didn't create any threads before going into a loop with CheckSynchronize(2147483647). It just didn't seem to work. Looking at classes.inc, I have now found out that it has sanity checks which make it ignore the timeout when there are no threads created. Shouldn't this be mentioned in the docs?
