I'd like to see this revived, getting a bit tired waiting longer and
longer to see isolationtester complete. Is it really a problem that we
require a certain number of connections? Something on the order of 30-50
connections ought not to be a real problem for realistic machines, and
if it's a problem for one, they can use a serialized schedule?
