Spurious failure of 'merge' due to cleanup of /tmp

["Daniel L. Rall" <dl...@collab.net>]

On my Mac OS X 10.4 system, something deleted the contents of /tmp
while the test suite was performing a 'merge', including the REPORT
that Subversion had spooled to disk:

svn: Can't open '/tmp/report.tmp': No such file or directory
Traceback (most recent call last):
  File "/Users/dlr/src/subversion/subversion/tests/cmdline/svntest/main.py", line 924, in run
    rc = apply(self.pred.run, (), kw)
  File "/Users/dlr/src/subversion/subversion/tests/cmdline/svntest/testcase.py", line 121, in run
    return self.func(sandbox)
  File "/Users/dlr/src/subversion/subversion/tests/cmdline/merge_tests.py", line 4200, in avoid_repeated_merge_using_inherited_merge_info

  File "/Users/dlr/src/subversion/subversion/tests/cmdline/svntest/main.py", line 271, in run_command
    None, *varargs)
  File "/Users/dlr/src/subversion/subversion/tests/cmdline/svntest/main.py", line 370, in run_command_stdin
    raise Failure
Failure

Albeit whatever performed the deletion was probably wrong for doing so,
do we take any steps to protect against this type of problem?

What sort of step could we take?  I don't see how you can prevent
files from being deleted by other processes...

Failing fast seems like the right option to me...
