Witty.
I skipped the technicalities and opted for a silly response, but apparently you want to hear them. It would still lock up the simulation thread. Depending on how they decided to write the game, the simulation thread typically spawns numerous threads to handle IO, physics, AI etc simultaneously. The simulation thread then waits for all threads to complete before restarting its loop. If whatever thread combat is running on never completes due to said retarded loop conditions, you're hooped.
Please don't turn this into a programing debate.
