Is it a service, or is it a compiler?

It seems that the main differences are whether:

- the state is in some special form, or on the file system.

- the processing code is resident in a process

The two are related.  Essentially, a service is a cached compiler: in
that it operates on an in-memory data store, using in-memory code.

These caches ar a real thing btw.  Many environments take a long time
to load.  (Essentially, compile or link themselves into existence.)

I wonder if there is a simple way in linux to snapshot an in-memory
state in a VM so it can restart very quickly.
