I reworked Gennady's umid OS abstraction patch because the code shouldn't be moved entirely to os. As it turns out, I moved most of it anyway. This patch is the minimal one needed to move the code and have it work. It turns out that the concept of the umid is OS-independent, but almost everything else about the implementation is OS-dependent. This is code movement without cleanup - a follow-on patch tidies everything up without shuffling code around.
