Hi all,
I have two problems at the moment building and running Stackless on OS X
(10.2.1 "Jaguar"). The build problem is that the _socket extension is
failing as follows:
-----

The second, runtime, problem is that I get an segv fault when a channel
"runs out":

There's no stack trace in the crash log for some reason (is this a
side-effect of being stackless?).
Any ideas welcome. I'm happy to dig into the code and run debug stuff if it
helps.
