I guess in the long term a project like wine, if successfull, doesn't
have to live with the restrictions put up by the environment. If I
understand correctly, the reason we have to do this nasty stuff, is
because the kernel is missing functionality, which the NT kernel
provides. Linus has stated that he thinks the Wine project is pivotal
for Linux success as a desktop operation system. The kernel guys have
been pretty cooperative before and I'm sure if we tell them what we
need, or even better help out implementing it, Wine could be just
another toolkit, perfectly well integrated _with_ the Linux environment.
Let's just look at the problem with the memory layout. Wine relies on
the possibility to load certain codes at fixed addresses as this is
how it works under windows.
Linux choose exact the opposite direction, i.e. try to ensure that
libraries are loaded at random places in the memory. This is not a
missing feature it is a complete different design decision. And I
seriously doubt that the kernel/or glibc guys will import the security
flaw from windows to always load code at fixed positions.
So wine will have to live forever with it's custom preloader hack to
emulate the windows process environment.
You don't seem to realise that you can execute wine-pthread or
wine-kthread directly instead of executing wine-preloader. I doubt
companies using Wine will care (since the same security flaw will affect
Windows and will have to be patched with urgency) and if they do then
they can compile their app as a winelib app, which uses the OS's dynamic
loader and whatever security benefits come with it.
Your arguments seem to centre around complaining about the baggage that
Wine brings around with it, yet that we emulate the Windows environment
so well is the very reason that a Wine port is so much cheaper for
companies than a full port.
