By putting the files in /tmp you will be putting them in a place where JTREG won't deal with them. Also, in the event of a test failure, will the file in /tmp be left behind?

Oh, Dan is right :-( With jtreg, I can use -retain to keep the temp files, otherwise jtreg cleans them up.That only works oc with cwd.

I see now how weirdly difficult this problem is. In my opinion, the file handling parts of the UL tests would have been better left as jtreg tests, not as gtests.

For the record, I would be perfectly content with just the assert->ASSERT part of this fix.
