As a matter of fact (unknown to me earlier) Dropbox is already using a
private backport of this patch. So it won't affect Dropbox's decision
anyway. But it might make life easier for other, smaller companies that
don't have the same resources.

However this talk of "wasting our time with Python 2" needs to stop, and if
you think that making Python 2 less attractive will encourage people to
migrate to Python 3, think again. Companies like Intel are *contributing*
by offering this backport up publicly.
