There are two cases were DrDr kills stuff. Case 1 is when there's a
timeout, but you aren't close to that. Case 2 is when DrDr itself
crashes and needs to get a clean slate of system resources. I think
this is unlikely to be the problem, because the DrDr instance that
crashed would be the one listening to the test's output not the one
that did the killing. But I can look into it.
