Not any more. I fixed that about an hour ago.

Yes. SConstruct now sets an environment variable that overrides the
default SHM key. The separate TCP port is allocated using the port-zero
trick you dug up.

Yes, I thought about that. In theory the environment variable could
be set to a base value plus the SConstruct run's PID. But running multiple
tests concurrently doesn't make a lot of sense, so I haven't actually
implemented this yet.
