Doing this sort of thing completely defeats the purpose of LD_PRELOAD.

It's there to help old binaries work with new binaries.  I used it to keep
an old Motif library from dying because it couldn't find _Xsetlocale when
glibc got decent locale code (yes, I was using a libc5 shared object with
glibc -- don't try this at home, folks).

The canonical use is "LD_PRELOAD=blah /usr/local/bin/blah" -- it's
designed to be a case-by-case thing.

I think it's been there for some time.  At least a year.

*chuckle* Probably.

I was planning on saying something nasty here, but I'll refrain.  Those
who know me know what I was going to say anyway ;)
