Subject: Fix queueing-up unhandled messages without pushback
X-Git-Url: https://git.xandkar.net/?a=commitdiff_plain;h=6c4ca91c4760f69d559ab7be98846c57daffbe19;hp=6c4ca91c4760f69d559ab7be98846c57daffbe19;p=khatus.git

Fix queueing-up unhandled messages without pushback

by skipping sleep when there're open FDs (which can be written to during
sleep).

While this doesn't grow the queue, this still prevents pushback by
allowing data to be written before reader can reach EOF.
