Dealing with Deadlock Problem

In general, there are four strategies of dealing with deadlock problem:

1. The Ostrich Approach

Just ignore the deadlock problem altogether.

2. Deadlock Detection and Recovery

Detect deadlock and, when it occurs, take steps to recover.

3. Deadlock Avoidance

Avoid deadlock by careful resource scheduling.

4. Deadlock Prevention

Prevent deadlock by resource scheduling so as to negate at least one of the four conditions.

Now we consider each strategy in order of decreasing severity.
