Some users of Thin reported crashes with this in the logs: 

ruby: ed.cpp:607: void ConnectionDescriptor::_WriteOutboundData(): Assertion `nbytes > 0' failed.

Any clue what's wrong?

I believe this is a kqueue bug [?] The test that causes it to fail is connecting to a server and writing nothing. EM is 'expecting it to write' immediately, as it arms it for writable immediately. I have, however, seen this in other circumstances, but that seems most obvious. The others were when it was under super heavy load for like a minute.
