Too many orphaned processes on OSX in Rails

This should be reported on https://github.com/thibaudgg/rb-fsevent

That's because Rails Spring listener creates the forks and rb-fsevent creates the processes.

Listen can't really do much here to fix this (as far as I know), unless the watchers aren't being closed properly.

There's also a quite recent commit like this: guard/rb-fsevent@c9deae0

So you may want to try different rb-fsevent versions (including earlier ones) - or even build a gem from the rb-fsevent master branch.

Also, Listen (or rb-fsevent) may be crashing - and not closing the processes for some reason.

You may want to try running Listen in debug mode with an environment variable like: export LISTEN_GEM_DEBUGGING=1 or export LISTEN_GEM_DEBUGGING=2.

You might want to check if the above code in rb-fsevent (for killing the process and closing the pipe) if it actually works.

@e2 don't really want to test it out, as I found a workaround, and I don't want to have to reboot.
