Thanks for the explanation!
It occurs to me that using an OS such as eCos, where we would replace
processes with threads anyway, the marshalling wouldn't be required, though
we would need to protect the WIN32 API adequately from unwanted reentry.
Maybe it would be worth adding pseudo-multi-app support under Linux too, to
make the WIN32 API applicable to more users until real multi-app support is
there.

I've just heard that the wxUniversal port project has just got their menu
implementation working...
