Eric Lindvall commented on ZOOKEEPER-1756:
------------------------------------------
Okay. I'll check it out when I have some time (I'm not sure when I'll have a
chance to get to it).
The issue isn't a blocker for me, because I'm applying this patch as part of
the build process of the zookeeper gem, but for anyone else using the C client,
it's going to likely make a difference for how well they handle server timeouts
(it's made a huge difference in production for me).
> zookeeper_interest() in C client can return a timeval of 0
