Detailed Description
A block allocated from the operating system.
tm_blocks are parceled into tm_nodes of uniform size based on the size of the tm_block's tm_type.
All tm_nodes parceled from a tm_block have the same tm_type.
A tm_block's address is always aligned to tm_block_SIZE.

| char* tm_block::end |
The end of allocation space.
When alloc reaches end, the block is fully parceled.
