Need ability to dump world without exiting

[blakemcbride]

Oaklisp provides the ability to dump/save a world image upon exit. This is great but has two problems. First, the user must know before hand that they will want to save an image later. Second, they must essentially hard-code the name of the single, at-exit saved world file.

What is needed is the ability to save a world through a method call to a specified file without exiting the system. something like:

(save-world "myworld.bin")

A load-world would be great too but less important.

That's a good idea. I don't think there's any particular technical barrier: the process could fork before doing the destructive machinations required to prepare the world for saving. We could just allocate a new bytecode instruction. Certainly this would simplify other aspects of the system, because things could be migrated out of the emulator and into user code.
