I'm not entirely convinced this is a good idea, because IIUC, what this
is in effect doing is having a zero second timeout. Previously we would
wait forever, currently we wait upto 30 seconds IIRC, and now we'll
wait 0 seconds. I think this will create lots of spurious timeouts
for applications to needlessly deal with.
