==============================================================================
Goals:
reproducible without history effects -- no out of memory errors on weird map to map changes
allow restarting of the client without fragmentation
minimize total pages in use at run time
minimize total pages needed during load time
Single block of memory with stack allocators coming from both ends towards the middle.
One side is designated the temporary memory allocator.
Temporary memory can be allocated and freed in any order.
A highwater mark is kept of the most in use at any time.
When there is no temporary memory allocated, the permanent and temp sides
can be switched, allowing the already touched temp memory to be used for
permanent storage.
Temp memory must never be allocated on two ends at once, or fragmentation
could occur.
If we have any in-use temp memory, additional temp allocations must come from
that side.
If not, we can choose to make either side the new temp side and push future
permanent allocations to the other side. Permanent allocations should be
kept on the side that has the current greatest wasted highwater mark.
