What it seems to be is highly variable. Looking at calliphoridae's
last half dozen successful runs, I see reported times for
027_stream_regress anywhere from 183 to 704 seconds. I wonder what
else is happening on that machine. Also, this is probably not
helping anything:

'extra_config' => {
...
'fsync = on'

I would suggest turning that off and raising wait_timeout a good
deal, and then we'll see if calliphoridae gets any more stable.
