As I was resuscitating my buildfarm animal lousyjack, which runs tests
under valgrind, I neglected to turn off force_parallel=regress in the
configuration settings. The results were fairly disastrous. The runs
took about 4 times as long, and some steps failed. I'm not sure if this
is a known result, so I thought I'd memorialize it in case someone else
runs into the same issue. When I disabled this setting the animal turned
to being happy once more.
cheers
