After digging into this a bit more, I think ergo's testsuite is
inheritly not parallel-safe: it uses no subdirectories and a default
output file ("ergoscf.out") which it only renames to something
test-specific on failure.  There's also intermediate binary files like
"density.bin" and above mentioned ergoscf.out gets removed at the
beginning of a test...

There does not seem to be a safe way to tell ergo to use a different
name as output file (it's not using stdout by default).

So I will see about forcing parallel to off for this package.  Not sure
what this will mean for the timeouts seen on some buildds, though.
