Depends on: 170628
Blocks: 159775
Bug #170628 adds capabilities to pre-allocate fast memories early to avoid fragmentation, but this is currently disabled because it's still possible to obtain bimodal performance numbers when stressing fast memory allocations.
Fix the underlying issues, and pre-allocate again.
Or close this as won't fix by making fragmentation at runtime a non-issue.
Also see bug #170773 which suggests giving up cached fast memories at runtime if they haven't been used in a while.
