LD_PRELOAD doesn't exist on Windows. And on Linux, it can be a big hassle
to use it: The section "GLIBC" in the plasticfs-1.9/BUILDING file in
http://plasticfs.sourceforge.net/ is frightening. It implies that in order
to use LD_PRELOAD with glibc in some situations, it is required to rebuild
glibc with a particular configure option and use the rebuilt glibc inside
LD_PRELOAD as well. Thus basically libc gets loaded twice by every program.

Yes, but if it's too much of a hassle to use, it doesn't help us.
