Operating System - Deadlocks

Do you think though that prevention of deadlocks though could be more CPU intensive than just letting it occur?
My answer:
Yes, in my opinion it might be quite true that prevention of deadlocks could be more CPU intensive than just letting them occur. Priority setting when a deadlock occurs is how issues are treated today. CPU time and memory might be limited in cases where a mechanism to prevent any deadlocks is attempted to be initiated. Deadlocks can be difficult to solve, but the occurrence of deadlocks is inevitable in any multi-tasking, multi-user operating system, and developing and/or initiating a system to prevent the occurrence might be too complicated for CPU's with current levels of capacities to handle.

It certainly is something that can always happen. What would be the most efficient way to handle a deadlock when it occurs?
