test_system.SystemTest.test_filesystem fails on OSX 10.9

[markberger]

This might be a 'not our problem' ticket, but the test suite fails on OSX Mavericks running Python 2.7.5.

When I run the entire test suite I get this callback:

Node._startService failed, aborting

When I run the test by itself, I receive this callback:

Duplicate of #2023 (on a different platform)?

[zooko]

markberger: Daira and Brian did some good analysis of #2023 at the Summit in San Francisco, on one of the days when you weren't there. They were somewhat stymied by not having a machine on which the problem was happening. (The problem happens on some buildslaves which are FreeBSD or Slackware buildslaves, IIUC.)

Maybe we can debug it, now that a similar or identical problem is happening on your Mavericks system!

I'm pulling this into the 1.11 milestone because I believe that the patch for #2023 (​https://github.com/tahoe-lafs/tahoe-lafs/pull/108) will fix this (in fact I'm more confident that it will fix this than #2023).

#2287 was a dup

Landed in [d27a57cb49], merged in [d91170a7acd], although for some reason the auto-notify hook didn't see fit to add a comment here.
