[Python-Dev] Having extensions builtin

[Martin v. Loewis]

With the new distutils configuration scheme, it appears to be
difficult to build modules in a non-shared way. Building modules
non-shared is desirable when freezing is attempted, and also to reduce
the startup time and memory consumption.

It is still possible to add modules to Setup or Setup.local, so that
they will be build into the interpreter. However, setup.py will still
build them in a shared way afterwards. I propose that setup.py builds
only those modules that are not builtin.

Martin
