> After investigating an issues with [hanging threads|http://mail-archives.apache.org/mod_mbox/zookeeper-user/201106.mbox/%3Citpgb6$2mi$1@dough.gmane.org%3E] I noticed that any java.lang.Error might silently kill the SendThread. Without a SendThread any thread that wants to send something will hang forever.
> Currently nobody will recognize a SendThread that died. I think at least a state should be flipped (or flag should be set) that causes all further send attempts to fail or to re-spin the connection loop.
