I just started a storage server node on a filesystem that was mounted read-only, and it failed to start, emitting:

client node probably not started

I guess _clean_incomplete() should catch, log, and ignore any failure to clean the incoming directory.

Josh and I are going to fix this in our work on #999. Bumping it out of Milestone 1.9.0 and into Milestone "soon".

sounds like an easy in for 1.11?

1.11 is frozen for work on new tickets, but it would be nice to have the the ability to run on a readonly filesystem for 1.12. I'm not sure this is the only bug preventing that, though.
