Fix is now pushed to master. Not perfect, but very stable.

So the PMTUd thread is somehow busted. I have attached a disable-pmtud
patch that expects the mtu to be 1500 on the ethernet interface.
With this patch I don't see any wonky membership changes and only from
time to time (specially when membership is forming) retransmits, but on
a 4 node cluster cpgbench can run smoothly over and over without issues.

Hey Chrissie,
I also found the issue that's causing membership to take a long time to
form and random changes. It is somehow related to the PMTUd thread
that's doing something funky. I have an idea of what's the root problem
but i'll need to do proper debugging / investigation.
