I assume your userdata has __gc metamethods, is that right? Then, they
are collected in two phases: in a first GC cycle, their metamethods are
called; only in the next cycle they are actually deallocated (if the
metamethods did not "ressurect" them). That may (or may not :) explain
part of that behavior.
