> ASyncHammerTest is failing intermittently on hudson trunk. There is no clear 
> reason why this is happening, but
> it seems from the logs that a session connection to a follower is failing 
> during session establishment - the
> failure seems to be a problem either on the follower or leader. The server 
> gets the session create request, but
> it stalls in the request processor pipeline. (we see it go in, but we do not 
> see it com eout)
> unfortunately all efforts to reproduce this on non-hudson trunk have failed. 
> Even trying to reproduce by
> running on hudson host itself (manually) has failed.
> We need to instrument the client session creation code in the test to dump 
> the thread stack if the
> session creation fails.
