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)
