Covered by our pagein hackery, so given the apparent reluctance to add
advise to ld.so, we will have to keep it around for now...
Though the pagein list was created once, and isn't really reviewed
regularly ? There was definitely a period of a few months a year or two
ago when the pagein list contained libraries which had been removed, so
are we confident that the list that's there at the moment make sense ?
Guess no (not well maintained). So, sure, a more generic approach would
be better, not the least from a maintenance viewpoint.
