It's because there's a System beep somewhere in there and I was just
interjecting the question-- why the heck do we have System beep(s)
embedded in the system?

But let's please not focus on that right now.  I really want to ask
the more important question whether there's a problem with Cog.

None of the symptoms happen with the Interpreter VM (2357).

You can easily reproduce it yourself with Cog.  Just start the base
Squeak4.5 image with the -mmap 2000m argument.

Then, in a workspace:

   self halt.

Do It, then press Proceed on the debugger that appears.

Does the problem occur for you too?  It's related to amount reclaimed
by the garbage-collector, but clearly we're not out of memory....
