Freeing of preq in all the callers of this one looks sensible,
except for the one in finish_request() of http-push.c that pulls an
preq instance out of request->userData.

Can somebody help me follow the dataflow to convince me that this is
not leading to double-free in start_fetch_packed()?

Thanks.
