[Labs-l] Webservice

[Petr Bena]

Until we get a stable solution I hacked out this C code:
https://tools.wmflabs.org/paste/view/41f0da78

you can just run this as your tool on tools-login or tools-dev, it
will fork() a daemon, that runs less than 500kb of operating memory
and checks every 20 seconds if your webservice is running and if it's
not, it will spawn it.

I copied it to /shared so your can just run:

/shared/keeperd

on toold-dev as your tool and it should do the checks...
