Not all C programs run on multi-user systems, and not all computers
have operating systems or clocks. A large part of my output is for
stand-alone processors, the ones that go on modem cards and the like.
I HATE timing loops - someone is sure to put in a faster chip without
telling me - but sometimes it is the only way to do things. I
therefore rely, if I can't avoid it, on the compiler not optimising
out 'empty' loops.
