+1 from me.

These are very specific to CPython's style of garbage collection - they 
don't make sense in the context of something like the native GC in 
Jython or Ironpython.

So -1 on moving these to gc - put them in the new interpreter-specific 
module along with everything else.

I wouldn't bother moving these two - there is lots of import related 
stuff in sys already (path, path_hooks, metapath, etc) and it isn't 
worth the hassle of trying to move all of it.

'interpreter' seems unnecessarily long. '_pyvm' would get my vote, 
although I'd also be fine with pyvm or cpython (it will be necessary to 
get Guido up to at least +0 just so he can choose the name!).
