erlang:halt/1 is broken

[rlipscombe]

We're looking to create an Erlang crash dump, by erlang:halt("Whoops").

However, instead of creating the crash dump, the Erlang VM dies hard with the following:

Bad file descriptor (epoll.cpp:69)
Aborted

This appears to be in deps/erlzmq/deps/zeromq3/src/epoll.cpp, from zeromq-3.2.2.tar.gz.

This happens on Ubuntu and Mac OS X.

Well, actually, it turns out, I do get an erl_crash.dump file, but it's truncated.
