OK. There are a few issues:

That's just a dumb message, as it's not running in threaded mode, AND
the request isn't being process in a child thread! I've committed a fix
which prints that message only if there is really a child thread that's
unresponsive.

I think what's happening is that the request is being free'd in a
place where it doesn't expect it to be free'd.
I've re-arranged the code to note, and catch this race condition. It
works in my tests, but my tests didn't see this race condition in the
first place...
