Oh, an LD_PRELOAD could do that on Linux (although it couldn't override
stuff opened by glibc itself I think, like the locale databases, at
least not in glibc-2.3).

But *changing* it while the program was running without the program
knowing is the sort of thing that needs kernel assistance that's not
there --- well, not in stock Linux. User-mode Linux could probably do
it, as could something like MOSIX (when you think about it process
migration really *needs* this sort of thing...)
