Great, that is definitely progress!

Yes, stale furl files can definitely cause problems if you are not using
persistent furl files.  Currently, ipcluster assumes that you will be using
a shared file system that all the engines and controller can read in the
same location.  Thus, we don't yet expose options like this to ipcluster.
BUT, we are in the middle of completely refactoring IPython's config
system.  Part of that work will be to make ipcluster more configurable.
This should happen sometime in the next 2 months.  In the meantime if you
have patches to add such an option to ipcluster, that would be fine.  Keep
us posted.

Cheers,

Brian
