[Gtk2hs-devel] problem with finalizers and concurrency

[Axel S. <Axe...@en...>]

Pete et al,

I think we need to hold off a release for now. I just tried the
following:

aconit:/aconit/source/gtk2hs/demo/concurrent:1042$ gdb

Thus, there's something fishy with finalizers and currency. I'll try to
investigate.

Axel.
