That DLLs directory seems to be a way which we can follow in our own

The disadvantage is that all DLLs are read, whether they're imported, or

My suggestion is: "import foo" searches for a foo.ipyd (which basically
is a renamed foo.dll) in the search path, and can use both pyc-compiled
and handcrafted dlls.

Our use-case is to re-implement the API of 3rd-party native cPython
modules (like pysvn in my case) in C#. This should work as a drop-in
solution - drop the .dll in some appropriate place, and "import pysvn"
works without any changes in the actual application.
