block processor: recycle blocks to reduce allocation pressure
Instead of freeing/allocating blocks all the time in the locked, serial path, use a free list to "recycle" blocks. Once a block is no longer used, throw it onto the free list. If a new block is, needed try to get one from the free list before calling malloc. After a few iterations, the block processor should stop allocating new blocks and only re-use the ones it already has. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
