Just a thought : why couldn't ndiswrapper set apart some piece

Like http://article.gmane.org/gmane.linux.drivers.ndiswrapper.general/4737

It's dirty, I know, but after all they are executing win32 code ...

Why wouldn't this work ?

I think this would be a good idea. I don't see any reason in principle why the ndiswrapper code couldn't use a separate stack for the Win32 driver code. Sharing the stack between the Linux kernel and whatever junk is going on inside the Windows driver seems rather inherently fragile..
