FIFOs have some bizarre properties which might be related - for instance,
opening a FIFO for reading will block until something else opens it for
writing (the open() call itself blocks, not just attempts to read). Could
it be that an unexpectedly blocking system call is stopping the heartbeat
and causing IPython to think that your kernel is dead?
