Windows these days does delays with timing loops or the scheduler. It
doesn't use a "port". Also, Windows XP only supports machines that tend
not to have timing problems that use delays. Instead, if a device takes
a while to respond, it has a "busy bit" in some port or memory slot that
can be tested.
Almost all of the issues in Linux where _p operations are used are (or
should be) historical - IMO.
