Before MultiFinder, you could just read MemTop.  Now, MF diddles
MemTop to spoof applications that depend on it in perverse ways.
There is a new method described (incorrectly) in The Macintosh
Programmer's Guide to MultiFinder (6/3/88) with a correction noted in
Tech Note 205.  I haven't got the former, but what I glean from the
latter is that _MFMemTop returns a pointer to the top of physical RAM.
