This is done by evaluating "UnixProcess saveImageInBackgroundNicely".
The image will be saved by a copy of your Squeak image running in a
separate OS process at low priority, with little or no impact on your
main Squeak process.

It should also work on OS X if you are using the unix VM for OS X that
supplies the OSPP plugin (I would appreciate if someone can confirm
this). It might also work on the regular Mac VM if you compile your
own OSPP plugin, but I'm not sure of this.
