That was my "translation" of the os.kill* because I assumed a shell
command would be easier to understand.

Both os.kill(-pid) and os.killpg(pid) should do exactly the same
thing.  I guess buildbot just tries everything possible because it's an
area where not all Unixen are in agreement.

is the & above literal?  Are you sure you don't mean && ?
