	Plans for making AFFLIB multi-threaded:

	Low hanging fruit:
	* Compress in background
	* Calculate hashes in background

	Easy implementation strategy:
	* mutext for:
	- the entire cache
	- each page of the cache
	- the TOC (should this be re-implemented as a C++ vector?)

	Both compressing and hashing needs access to the page cache in another thread:
	- Needs to lock the page cache so no other process will write to it.
	- Or needs to make a copy of it.
	- Then needs to write it out.


	Test program:
	- Can we write a method that computes hash in another thread?
