First function removed from Unix MPM's and moved to a common file. This

work is not anywhere near finished, but the cleanup has begun at least.
Had to make a couple of variables non-static, so a name change was required
since they are now viewable from outside the library.  The advantage to this
is code that is much easier to maintain into the future, because it is
duplicated less often.
