The reason it works is that Multifinder allocates memory for applications
starting with the top of memory and working its way down.  This makes it
possible for the system heap (which is at the low end of memory) to expand
as needed.  

I believe that Excel requires that it be loaded low in memory, and that
Multifinder contains code to accommodate this need.  Since most application
are loaded high, the low end of memory will usually be free, regardless
of the order in which application are run.
