Hi all,

Thanks for sharing all this wisdom!

Actually at der Freitag we use this script[1] to warmup any worker that is
restarted due to too much memory consumption or due to new deployment
version.

I hope it helps someone!

Oh, and credits go to Timo as he did the original version, I just messed
with it from time to time.

Cheers,
Gil Forcada
