- * Regional allocator. Allocates small portions of of larger chunks.
- * Based on region-allocator from NSD, but rewritten to be light.
- *
- * Different from (nsd) region-allocator.h
- * 	o does not have recycle bin
- * 	o does not collect stats; just enough to answer get_mem() in use.
- * 	o does not keep cleanup list
- * 	o does not have function pointers to setup
- * 	o allocs the regional struct inside the first block.
- * 	o can take a block to create regional from.
- * 	o blocks and large allocations are kept on singly linked lists.
