Passenger hangs on live and SEGV on tests possible threading / kernel bug?

[Steven Hartland]

We're having an issue with Passenger on FreeBSD where it will hang
and stop processing any more requests the details are attach to
the following bug report:
http://code.google.com/p/phusion-passenger/issues/detail?id=318#c14

In addition the test suite crashes in what seems to be a very
basic test, which I'm at a loss with.
http://code.google.com/p/phusion-passenger/issues/detail?id=441

I'm thinking this may be a bugs in the FreeBSD either kernel or
thread library as the crashes don't make any sense from the
application side.

Any advise on debugging or feedback on the stack traces would
be much appreciated.

    Regards
    Steve
