Sorry for the delay. I've just come back from some meetings and then
FOSDEM. I'll get to work on this bug.  But again I do not consider it
a blocker, certainly not for release. There are workarounds for it
(disable frame-filter all), for the cases of exceptionally long
backtraces.

It is  unfortunately a non trivial issue having to do with both Python
interrupts and GDB exceptions, so a fix has to be carefully tested.

Cheers

Phil
