I'm misremembering. SIGINT seems to work okay, it's SIGTERM that leaves
orphaned children (with ppid 1) around with rake, presumably because it
doesn't catch that signal. Same with drake (0.8.1.11.0.1)

Thanks, I tried `drake &' folllowed by `kill $!' (using bash) and the forked
drake children revert from ppid $! to ppid 1. A `killall drake' is required to
clean up.
