Not yet... ;-)
We both missed an _important_ point. Currently we're converting
the string almost always twice! That's what we wanted to avoid by
pre-allocating and keeping the buffer around, didn't we?
See my commit in r 8211.
BTW.: I tested the mechanism by using a few printf's, and it looks
like the buffer gets allocated with only a few hundred characters,
if at all (normal widgets like in [test/] hello.cxx, valuators.cxx,
and tabs.cxx use slightly more than 100. The longest I found is
test/editor that allocates a buffer for the longest line that is
displayed (even if it is clipped), but I think that doesn't matter
at all.

You're welcome. Thanks for your continuing work on really difficult
internal issues (OS X, X11, Windows GDI). That's amazing!

generally, yes, I think so, but wait a moment...

I'll take a look at this (and maybe test on Cygwin whatever I find)
and let you know...
