That won't work. The kernel can't wait for spawned processes to finish 
because it is holding locks.

The script could as last operation trigger a manual reset, but that 
would not be the same as a timeout reset because you don't know the 
cause of it and would always need to do a full engine reset.

Sorry, but what you are suggesting here (collect data and then reset) is 
not easily doable.
