Somewhere between 2 and 3 the request is prematurely freed. Any ideas? Is
there a libevent request kill capability that could be "cleaning up"
requests without me knowing?
Also, is there any way I can verify whether or not a request exists before I
try to mess with it. At least to avoid the SIGSEGV.
