Yea, I had forgotten about that bit.

I do get regular issues, although the happen to not end up in visible
failures.  All the tests output their regression.diffs into the same
place - which means there'll every now be a failure to remove the file,
and if there were an actual failure it'd possibly end up being
attributed to the wrong test.  So I think we need to relocate that file
to be relative to the sql/ | specs/ | expected/ directories?

Curious about the test decoding thing - hadn't seen that here.
