[LRUG] Making Rails time out

Fri Apr 19 07:54:22 PDT 2013

A long sleep is indeed required and I was (probably sadly) interested in
your question :) We've struggled with this too and I had not found a
solution.

On a side note, if you're lagging this Friday, watch what happens when you
wring out a washcloth in space. Kept me awake for 3 mins at least. (From
ycombinator.)
