+This is based on Doug Lea's allocator but rewritten so I can read and understand it...
+also features of free all-at-once pools are added.
+Now uses 16 byte alignment, which does increase the minimum allocation size to 32 bytes
+including the overhead.
+Improved bit block scanning by using a count leading zeroes instruction.
