Several people have said you can have either a reset-proof _or_ a
resizeable ram disk, but not both.  Could it work like this:
The reset proof ram disk would be by the normal bootup method of
telling TOS a new top of memory.  The resize ability would not
necessarily have to be able to occur within a program, since many
allocate all free memory, but why shouldn't it be able to occur at
the desktop level?  Somehow TOS would have to be forced to recognize
a new top of memory without rebooting.  Does anyone know if thats a
doable thing?  It wouln't even necessarily have to be through a
legal TOS vector, the program would just have to check which version
of TOS it was running under.  It would certainly be handy.
