Questions: snapshot and process

Hi.

I have questions about Squeak system. I apologize for possible silly questions.

Say if I want to make squeak run without GUI, I should edit method "snapshot", so that the next start-up of squeak, some classes and objects need not start-up, eg controller and sensor. Is that right?

Where can I learn more about ProcessorScheduler? If I write a Squeak system that might run infinitely, I need process fork, to make way for GC and Sensors, etc. is that right?

Thanks in advance.
