Yes it is enough to encapsulate memory allocation and file functions into
python shared library. The python provide memory allocation functions, but
not all modules use them. File functions are hiden by posixmodule and python
modules can't use them.
except ... posixmodule gets renamed to ntmodule .... oh, i see what
you mean: python modules aren't allowed _direct_ access to msvcrtNN's
file functions, they have to go via posixmodule-renamed-to-ntmodule.
.... thinking about this some more... posixmodule.c is linked (by
default) into pythonNN.dll, thus making pythonNN.dll totally dependent
on a version of msvcrt.
This is not problem. If python*.dll hide msvcrt and other modules depend
directly from python*.dll I expect issue to be resolved. i.e.
python*.dll to be "portable runtime interface".
decoupling posixmodule.c from pythonNN.dll leaves the possibility to
make python independent of msvcrt versioning.
it would need to be a custom-compiled .pyd module, due to the early dependency.
i'll see if this is possible.
