[Vm-dev] OSProcess working directory under Windows

The Windows implementation of OSProcess is not very complete, and is much
less useful than the Unix/Linux/OS X implementation. That said, if you
also load CommandShell with OSProcess, you may find the path support there
to be of some interest. It maintains a "current working directory" for C:,
D:, ... more or less like Windows does.
