nonsharable files are allocated to jobs that eventually require other nonsharable and nonpreemptive resources and this is creating a recurring deadlock problem in your installation’s spooling system.

What features might you incorporate into the operating system so that deadlocks in the spooling system can be resolved without losing the work (the system processing) that was underway or already performed by the deadlocked processes?
