I've been writing DLL's since Windows 2000, and this has not been 
true for the entire time I've been doing this. As far as I know, 
*if* this was ever true, then it hasn't been true since Windows 
3.1. The global data segment is shared at the per-process level, 
no further. And I for one do *not* want to consider the absolute 
chaos that would ensue if it were any other way... \<runs away in
