Description

Memory deallocation in defer_temp_storage_destruction might be blocking. We should investigate if launching all the destruction kernels in sequence (or fusing destructors in a single kernel) before releasing the memory is any better to address:

// TODO Bury all the memory associated with the stream provider and then 
//      deallocate the memory

Research direction

Start by locating defer_temp_storage_destruction and the TODO about burying stream-provider memory before deallocation. Investigate whether sequential destruction kernels or a fused destructor kernel improves behavior, and define completion through measured evidence before changing the implementation.
