---------------------------+------------------------------------------------
Triggering this bug seems a little fragile; but the program and method
I've attached triggers the bug every time for me. It is minimal-ish, I
certainly have cut it down a lot, and it perhaps could be made even
smaller, but a lot of seemingly irrelevant changes to the file will fail
to trigger the bug.
{{{
$ cabal configure && cabal build
$ ./dist/build/deadlock/deadlock
}}}
And then edit the file and change the 1 to some other value, like 2.
Configurator will reload the file within a second, and then I see that
the thread that periodically writes something to standard out stops
working, and that CPU usage goes to 100%, and that I can no longer type
something in and have the program echo it back to me.
GHC-7.0.3 has no problem running this program.
