Whoops, I ran under the debugger some more and it looks like there are
still some crashes. 

Received Segmentation fault in LWP 3105 while waiting for SIGSTOP.

Program received signal SIGSEGV, Segmentation fault.

This kind of smells of a double-free or the like so I'll try leaving
it running overnight under gdb with MALLOC_CHECK_=2 set and see if that
sheds light on the matter.

(This crash seems to take longer to manifest than the other one in the
http code).
