Yes, I have!  Though I'm not yet enough of a Python wizard to build me
a working configuration the way I wanted to have it.  It's like 400
LoC shell script right now (the build master), plus a shell script
doing the actual building on the clients (160 LoC).

It basically builds as many crosscompilers on all nodes as possible,
until a new commit shows up. And once a new commit shows up, new build
jobs are only triggered if they're expected to finish before the last
of all currently jobs is expected to be done. Then, all builders are
updated and start building again.

If you have a few hours, you'd help substituting my scripts with
something that's possibly better cared for upstream :)

I just read the docs after verifying that the helper variables were
all common between gawk and mawk.

Probably it is.
