   This patch removes the asynchronous eviction of lineage cache entries from the GPU to main memory. Background eviction needs a compiler-assisted approach. A full runtime asynchronous eviction leads to synchronization issues. This patch also adds a flag to delete cache entries in GPU instead of coping to host.
   Currently, for a mini-batch workload with limited reuse opportunities, enabling reuse in GPU slows down the execution by 10x with eviction (copy to host) and 4x with delete.
