Ok, that should make maintenance much easier and will hopefully allow
you to stay current. In general we are more than happy to fix
regressions quickly if humanly possible. Any kind of experience you
gain from this would be very valuable, so if we could somehow end up
adding something to the Sage documentation about a large scale
deployment it would be a very nice result from this.

You can use ulimit to limit for example CPU time or memory used per
worksheet. See notebook? for an example.
