The main problem is the framework failures. I'm not sure exactly what's
going on, but IIRC occasionally a GHC gets an unexpected SIGALRM. Perhaps
Python isn't turning off its signals when it does fork/exec, or there's a
race condition somewhere.
The other problem is that there are some bogus ordering assumptions between
various tests, but these are straightforward to fix.
