I think you have two options:
*) inject code into the scripts to make them state machines
that will periodically check the timeout info and save the state to 
an object and reload it when it's restarted, similar to how the C#
compiler handles the yield construct.
*) use the threadpool as initially suggested: you will queue all
the scripts for execution. If a scripts takes lots of time to run,
the other scripts will be queued to other threads: since this should
happen rarely it should not be a problem, unless you also need
to guarantee against denial of service attempts. Note that this
means that the scripts will run concurrently.
