   Kudos to the dear soul who noted that multitasking on the Mac
could be saved from MapRgn()'s habit of ravishing the "free space"
between HeapEnd and the stack pointer (which will contain your 
code if you allocate new stacks in the heap!) by the simple 
expedient of resetting HeapEnd to the base of your stack.  
(Sounds scary, but it works....)

   Or it did.  Alas, perusing the shattered hulk of our application 
on the Mac II with MacsBug, it seems such bars will no longer 
restrain the madness, that this raving psychotic has been
paroled; we see all too clearly the "Mark of Zorro" 
(7fff .* 7fff) etched all across that lovely code.

   Gee, and it still works fine on an SE.  Suggestions, anyone?  

   "Well, Holmes?",
