        Actually you might find it interesting to read the "pnet/engine/lib_*.c"
files, this is where the Pnet's native methods are implemented. They are not
called native methods, but as internal-calls. These are not standardised,
and may be defined in any way you like. So Mono & Pnet have different
internal-calls and their classes abstracting these calls are not cross-
compatible.

        So lowlevel classes contain internal-call methods, and these in turn
are implemented in Pnet using OS native calls when necessary. So if someone
implements all the internal-calls in Pnet in a new CLR in a cleanroom fashion,
they can use the Pnetlib. Read the "pnetlib/doc/native.html" for a list of
all the internal calls.

PS: Native methods are methods *outside* the VM which can be called from
    a C# class. Internal-calls are methods *inside* the VM which can be 
    called using an abstracted C# method. eg...System.Math.Log()
