Hi Le, would it be possible to create a test that takes the memory-use-counts
before some activity, then after, with and without lexical-binding enabled, so
that we could fail if lexical-binding has bad behavior? I think that should be
more efficient, so I'd love to pin this down in an isolated case.
John
