OK, but the base question still stands:  the resetwarnings docstring doesn't
match what the code does:  is it intended to clear all warning filters
(that's what it actually does), or return them to the default state (which
is what it says it does, and the state that's there when the module is first
imported is about the only way I can read "default").
