(search for _osfile).
In this code, _osfile() is defined as a macro that makes a lot of assumptions
about the internal structure of an MSVCRT internal array. Additionally you
see code that indicates that in certain newer versions of Windows, they have
to *search* for a handle in memory in order to correct these assumptions.
To me, this means: Poisoned! Don't touch!
You're right. However, after seeing that all three of Perl, Python (see
http://bugs.python.org/file12950/__pioinfo.patch -- it's for different
reasons) and Ruby do it, I'm starting to think that it is almost a
necessity. :-(
