From 8e1b90ecc59573c4c5e9fc4934b4e30476b43e2f Mon Sep 17 00:00:00 2001 From: Jan Kiszka Date: Tue, 1 Feb 2011 22:15:46 +0100 Subject: [PATCH] Leave inner main_loop faster on pending requests If there is any pending request that requires us to leave the inner loop if main_loop, makes sure we do this as soon as possible by enforcing non-blocking IO processing. At this change, move variable definitions out of the inner loop to improve readability.
