[pypy-issue] [issue967] itertools.imap significantly (order of magnitude) slower than map or gencomps

[Armin Rigo]

Indeed, there is a special case for list(generator).  It's a bit annoying that
the more general list(iterator) is not sped up by the JIT at all.  It's a known
issue that we may fix at some point, but it's not completely clear how.
