The system clock tick is platform dependent. OTOH, the 0.001 limit for
the WAIT function looks like platform independent. Below the limit the
WAIT function doesn't wait at all, it returns "immediately" as my
measurements seem to prove.

You can find the functions here:

Moreover, I uploaded my Merge Sort implementation (I am using it since
Rebol 1.x days and this is not the first time I am publishing it):
