Reduce memory fragmentation during SBE updates
- Original code was repeatedly allocating/freeing 256K chunks of
heap memory
- Other tasks in the background fragmented the allocations and
could lead to out of memory conditions on large core number
parts
- Fix is to allocation one large chunk up front and use that for
all operations
