releaseDevice()

void KisSafeNodeProjectionStoreBase::releaseDevice

(

)

Notify the store that current projection device can be safely dropped. The store will try to recycle the device (taking ABA problem into account).

slotInitiateProjectionsCleanup

void KisSafeNodeProjectionStoreBase::slotInitiateProjectionsCleanup ( )

privateslot

After the projection has been used, we should clean it. But we cannot clean it until all the workers accessing it have completed their job.

Therefore we just schedule an exclusive job that will execute the recycling action in an exclusive context, when no jobs are running.
