I don't buy it. The minor performance difference is plausible, but not the
3x greater memory usage.

Wrong assumption on your part. Both BucketMM and FastMM release memory back
to the OS when it is no longer used by the application. I don't know how you
measure memory usage, but if you were using the "Memory Usage" column in
task manager then you wasted your time. The correct column to use is the "VM
Size" column.
