Just wondering, how did this happen?

How did *what* happen?

CLC in a nutshell.

How about this

DELAY=10

PotentiallyLongCommand &
PID=$!
(sleep $DELAY ; kill $PID) &
wait $PID

I just wrote a shell function:

ExecuteWithTimeout() {
local TIMEOUT=$1; shift
$@ &
local PID=$!
(sleep 10; kill -9 $PID) &
wait $PID
}

to use it type:

ExecuteWithTimeout 10 ipmitool blah blah bla

would kill ipmitool in 10 seconds.
