Not sure what the performance/security ramifications of this are, but seems that xbl is the leading cause of JSContexts. I get 31 JS_NewContext calls in a fennec startup.

We basically create one per script global (so one per proto document).
I'd think this is pretty cheap, though.

yeah, I haven't noticed any overhead in creating jscontexts. I'm not sure of the memory efficiency, etc.
Is there a reason you don't just swap out global objects?

It is not. JS engine will eventually get rid of contexts and this will get cleaned up in another bug.
