=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.
