Well, we came even closer. See [1] for a patch that fixes this by cleaning
BBT init and release.

Back then Boris suggested on IRC to wait for Peter Pan's BBT, which would
address this too.

It's interesting to note that: (1) the patch never got any formal feedback,
despite it was a fix; and (2) Peter Pan's work is still under development.

Guess I should have pressed the upstream buttons harder :-)
