[GemStone-Smalltalk] Problems starting my stone.

[Dale Henrichs]

Does the `HostAllocateFromReservedMemory` error happen every time you 
stop the stone?

The problem that I remember is that the error would show up after using 
the system for awhile. It's been a couple of years since I had a Mac 
laptop and it was several years before that that I recall seeing the 
issue of "sticky shared memory".

What version of the mac os are you using?
