Oh, incidently, I glanced inside the Linux kernel while working on QMAGIC 
library support..  It makes reference to "Converting ZMAGIC binaries" if 
the file start offset is too small.

I got the impression that it would be possible to convert the 1K file 
offset in the Linux ZMAGIC stuff to (say) 4K file offset start so that we 
can do proper demand paging to files rather than reading them into swap 
immediately...

Then again, I should know better than to say things like this before 
checking them out...
