That's not the way it works. These two are (usually) the main components:
key_buffer_size
innodb_buffer_pool_size
The rest are either too small to worry about, or per-connection, or something else.

This is probably the OS playing confusing games. A block can be in a limbo:
* Not specifically tied to a process and
* Identical to disk and
* Potentially able to be re-associated with the process.
No Swap is in use -- this is good.
