	I do this all the time.  If I understand Perry's code design,
AllocMem() allocates from the bottom of memory up, while VD0's allocator
grabs memory from the top down.  Assuming your RAM contents survives RESET,
you can play around in another Workbench for hours.  And as long as the
AllocMem() calls don't bump into VD0: area, it'll recover great.

	I use VD0: all the time.  And yes, I paid for it.  I sent in $700
for it, and got a 2M RAM board absolutely free!  Amazing.
