Ah, sorry. Fingers confused, typing error.

That should have read "fork off a new process".


e.g.

myProc := [this is my block that takes, oh lets say 3 hours to  
complete] fork.

Can I suspend myProc and save it to disk (seperately from quitting  
and saving the whole image)? Can I load it into different objects and  
resume it? Can I sneaker net it to a different machine and load it in  
a completely different copy of Squeak? Or will bad things happen?

As a quick experiment, I tried to "save and quit" squeak while I had  
a suspended process. Squeak locked up completely. I only tried it  
once, however. So that may have just been a bit of random misfortune.  
But it's the only time squeak has ever locked up on me.

I'm not sure where I'd ever use this. The SmalltalkImage stuff you  
mention is probably more generally useful. But I'm still curious.
