Description
When destroyCache() is invoked checkpointReadLock is held by exchange thread during all time cache entries are cleaning. Meanwhile, db-checkpoint-thread can't acquire checkpoint write lock and can't start checkpoint. After some time all page-memory has filled with dirty pages and attempt to acquire a new page causes IgniteOOM exception:
class org.apache.ignite.internal.mem.IgniteOutOfMemoryException: Failed to find a page for eviction [segmentCapacity=40485, loaded=15881, maxDirtyPages=11910, dirtyPages=15881, cpPages=0, pinnedInSegment=0, failedToPrepare=15881]

Checkpoint read lock in exchange thread acquired before GridCacheProcessor#prepareCacheStop(java.lang.String, boolean) method and inside GridCacheOffheapManager.GridCacheDataStore#clear() method.
