Yeah, I arrived at the same conclusion but can still reproduce a crash on
exit reliably (with the odd occasional good exit to confuse things). So yes
the same thing.

Yeah the code is wrong, I'm just concerned there is other wrongness lurking
in there, the one I see on exit is the same thing (deleting an already
deleted entry). I have some debug code in there now and will be looking at
it later today.

Around but busy.

We really should come up with a good standard reference counted pointer with
at least some debug stuff built in. It can go right next to our thread safe
string.
