Sometimes. If the executable/dll has been built with it's sections aligned
to 4k (page-sized) boundaries, it can be mmap-ed in, which means that the
kernel can share and demand page it. The DLL/Exe also has to have it's
sections loaded in the place it's requested - if it has to be 'rebased'
(moved to a different base address), WINE has to do a fair bit of work,
and scribble all over the code adjusting branches, etc. This makes the
affected pages not-shared.
Coincidentily enough, I've just submitted the patch that allows us to
mmap in the code to the WineHQ tree....it's already in the shipping
WPO2k tree. 8-)
