ci == ais_async_fd,  if there was something to read we should have
already had a callback.

These two that I mentioned last week:
  http://hg.clusterlabs.org/pacemaker/1.1/rev/34ae9f7b4675
  http://hg.clusterlabs.org/pacemaker/1.1/rev/19fdc0a3885a

I really doubt the patch is the right fix, conceptually, the node
can't be a member until the crmd process is running and done a whole
heap of processing.
So CRM_NODE_MEMBER without crm_proc_crmd makes no sense.

More likely, as-in the patches above, the process list wasn't being
updated correctly and thats what needs to get fixed.
It just never mattered before.
