[zeromq-dev] Assertion failure in fc.cpp:117

[Doron Somech]

So I suspect the pipe is being terminated before the messaging is being
read fully.

I made this patch to try to find out if the issue actually happen while the
pipe is being terminated, can you test it? If my guess is correct the code
should still assert but in a different place, which will help find the
problem.
