Well, wine is loading code at fixed positions. So we are bypassing this 
security mechanism, right? If I understand correctly, if the kernel/glibc 
guys will "fix" this, Wine will have major problems. 

This means there are many people (all wine users) dependend on being able to 
load stuff at fixed positions. Since we are doing it anyway, and if the PE 
loader would be integrated with the standard ELF loader, the kernel could 
make an exception for PE executables. That's what I mean about the 
environment adapting to given usage scenarios like wine. If this is too much 
of a security problem for a given system, one would'nt install wine anyway.

All I meant to say is that Wine is great and very successfull at working 
against the odds.
