This is from the repo_not_writeable test and was found by the OpenBSD buildbot:

#   Failed test 'expect failure when pushing to a repo with unwritable inventory
(format: --hashed)'
#   at repo_not_writable.pl line 40.
#                   'Pushing to "/tmp/64fKVmV6vG/r1"...
# darcs: waitForProcess: unsupported operation (Operation not supported by device)
# 
# '
#     doesn't match '(?-xism:failed)'
# Looks like you failed 1 test of 10.

This looks like it might be an intermittent failure.  Assigning to myself to
click the buildbot rebuild button and see what happens.

Indeed, this looks like an intermittent failure.  Yuck.

Are there reasons to believe this might be specific to OpenBSD?  Adding the
devel list so people see my question.

I guess we'll have to presumed-dead this one since it's not reproducible :-(
