The use of pickle to serialize the keys is a little bit suspicious if
there might be a reason to dump the filter to disk and re-use it in
another run of the program.  Pickle representation might change between
Python releases, for example.  It's just supposed to stay interoperable
between versions, not necessarily bitwise-identical.

Otherwise it's quite nice.  I'd suggest adding a .update() operation
that adds keys from a user-supplied iterator.
