> I have a btest test that can reliably crash proxies (on my laptop at least).  I'm not assigning this to the next release though because it just seems to be a case of filling the pipe between the parent and child and not the weird "poll 101" crash that is occasionally seen in some cases, I'm still trying to create a test to cause that crash.
> Here's the error you get from btest from each proxy since each proxy in the test crashes with the same message::

>   error: parent: 1317739862.781639 fatal error, shutting down communication: Resource temporarily unavailable [35]
