Did someone test the patch on a use case where the performance of
this macro matters a lot ? E.g. deallocating large lists or
dictionaries.

Todays CPUs have plenty of registers available, so it's possible
that the patch actually speeds up things, since the decref'ed
variable may well be an indirect reference. At the time Py_DECREF
was written, registers were precious golden flasks, only to be
filled with the most valuable of things ;-)

Just want to be sure we're not missing something...
