Sorry, I've been busy putting out another fire.  Yes, there's definitely
still interest.  I grabbed your revised patch and tested with it.
Unfortunately the timeout doesn't actually fire when requests are queued
due to queue_if_no_path; IIRC the block request queue timeout logic
wasn't triggering.  I planned to look into it more deeply figure out why
but I had to spend all last week fixing a nasty race and hadn't gotten
back to it yet.
