This smelled like a pool lifetime issue, and looking closer it looked  
like we were cleaning up a brigade after we had returned the backend  
to the pool. The attached patch stops the crash, and it seems to run  
at a sensible speed again (I suspect the late cleanup of the brigade  
was sending the code into a spin). Can you give it a try?

One proxy test still fails though:

t/modules/proxy.............ok 7/15# Failed test 10 in t/modules/ 
proxy.t at line 34
t/modules/proxy.............FAILED test 10
	Failed 1/15 tests, 93.33% okay

This fails because the first bucket of the response has been corrupted:

graham-leggetts-macbook-pro-3:httpd-test minfrin$ curl http://localhost:8536/reverse/modules/cgi/
sl/2.3.9-dev OpenS

I've seen this a few weeks ago and it went away, so I suspect this  
isn't proxy that's doing it. Need to dig further.
