Apparently not. :-( The call to _processoptions() won't hurt unless the user
invokes the interpreter with a -W arg.  Not much we can do there.  I think
the import in filterwarnings can be avoided by deferring the re compilation
until warn_explicit.  I'll see what I can come up with and submit a patch.
