I have. Not on debian, but on debianish system with dash. And the result was
that shellscripts are indeed the bottleneck. We still did convert to upstart
since we believed it would allow us to cut down the amount of shell scripts.
The event based architecture however forced much more shell scripting[1]
that made the boot time improvement much less than hoped.

        timeout=$((timeout-1))
