Fix broken locking so that at least the Python 2.2.1 grp test doesn't
lock up. This really needs to be looked at, as I don't think this
needs to be reentrant. In any case, several routines call the
__getgrent internal routine and it uses static vars for data. If this
stuff is really supposed to be threadsafe, then __getgrent probably
needs fixing.
