=D6=F7=CC=E2: Still getting a generator hang on 2.6.7
I've gotten around to testing the generator hang bug using stunnel under
2.6.7, and I still occasionally get the same problem. It seems to be around 50%
of the time. Here's some strace output from the generator and receiver from
two runs, one where the generator exits properly, and one where it doesn't.
Run 2 hangs indefinately.
