Yep that sounds about perfect.

I can't seem to get it working under 64 bit windows at the moment... keeps 
returning -ENOSYS and I'm wondering if windows and linux differ in their 
structure alignment or something. I remember this being a problem with vbd.

Btw, the choice of 'new' as a struct name in the tmem struct isn't necessarily 
wise... it might never come up but 'new' is a reserved word in c++.
