I was talking to the guys in #pypy (and I think some people from twisted 
were agreeing), who said that the whole _frame thing is not really an 
implementation detail, but a rather important interface. As such, I was 
thinking that maybe their underscore prefix should go...

I don't know how hard it would be for Jython, IronPython et al. to 
support this kind of interface, but seeing as how something like 
zope.interface relies on it (and therefore all of Twisted, too, I 
think), it's kind of mandatory anyway.
