I ran for over an hour with the Minish morphs going, no problem. But I can
get the image to hang in less than a minute by opening a bunch of bouncing
Tokenish morphs.

It would be interesting to try reproducing this in a Squeak image, but I
have not quite figured out how to make the Tokenish example work in Squeak.
Maybe someone with more experience in Morphic can try it.

Levente's suggestion of starting up a REPL loop to retain access to the image
is a good idea too.
