sim: Revert [34e3295b0e39] (sim: Fix early termination in mult...)
HG changset 34e3295b0e39 introduced a check in the main simulation loop that discards exit events that happen at the same tick as another exit event. This was supposed to fix a problem where a simulation script got confused by multiple exit events. This obviously breaks the simulator since it can hide important simulation events, such as a simulation failure, that happen at the same time as a non-fatal simulation event.
