Message11130

Somehow this process is broken on Windows. I am getting ValueError: bad marshal data. It however works fine on Windows if I use classfiles I created on Linux (i.e. with embedded CPython bytecode from a pyc-file). So the write-process must have some platform-dependent flaw.

Will investigate...
