NAME
	FreeMem -- deallocate with knowledge

   SYNOPSIS
	FreeMem(memoryBlock, byteSize)
		A1	     D0

	void FreeMem(void *,ULONG);

   FUNCTION
	Free a region of memory, returning it to the system pool from which
	it came.  Freeing partial blocks back into the system pool is
	unwise.

   NOTE
	If a block of memory is freed twice, the system will Guru. The
	Alert is AN_FreeTwice ($01000009).   If you pass the wrong pointer,
	you will probably see AN_MemCorrupt $01000005.  Future versions may
	add more sanity checks to the memory lists.

   INPUTS
	memoryBlock - pointer to the memory block to free
	byteSize - the size of the desired block in bytes.  (The operating
		system will automatically round this number to a multiple of
		the system memory chunk size)
