Since Boost support is my profession, I do not accept requests for
free support at my personal email; I hope you understand.  Please post
to the appropriate mailing list

Boost.Python leaks many things from that point-of-view; it is not
compatible with PyFinalize.  Until that gets fixed there's no point in
trying to clean up things like this.  Also, your change doesn't
properly clean up the remainder of the chains, so it wouldn't be the
right one to make even if it were appropriate to try to fix it.
