The above is for the previous command not the following.

Could you paste a bit more context from the previous command.
Specifically I'm wondering if the "Killed" message was displayed
(i.e. if the SIGKILL was actually sent).

I presume this is a race that you're seeing rarely.
I've never seen this, and I can't see the race.

What might be happening is the "sending signal KILL..."
message sent to stderr, is in a buffer somewhere,
which is dropped upon processing of SIGKILL.

What file system, kernel, shell are you using.

cheers,
Pádraig
