Comment:

 Nice work, bdew!  It's interesting that this happens only in
 [source:src/allmydata/test/test_cli.py at 20090609210509-92b7f-
 540d8762ba78bcb54be6775a376332d453ea2f7b#L1134
 allmydata.test.test_cli.Check.test_check], and only sometimes.  Examining
 that particular test case doesn't suggest anything special to me.  bdew:
 could you run the tests with the {{{--random}}} and {{{--until-failure}}}
 options of {{{trial}}}?

 Assigning this ticket to Brian -- it sounds like the foolscap eventual-
 send mechanism or Twisted might have a bug.  Oh, that's a good question --
 what versions of Twisted have we seen this on?  bdew's buildbot has
 Twisted 8.2.0: http://allmydata.org/buildbot/builders/BlackDew%20debian-
 unstable-i386/builds/1/steps/tahoe-version/logs/stdio .  midnightmagic's
 Twisted version isn't known.  There were two other people who reported
 this bug to me, but they didn't mention Twisted versions.
