I should have read what you posted more thoroughly. I apologize. A 
transaction timeout is surely a bad idea as Tom says below. Heck, not 
just from what he says below, but what about the scenario that killing a 
transaction could cause a massive rollback and thus increase the initial 
problem that I posted about :)
