If the proposal is to require the in-memory dso to already be properly mapped
(alignment, permissions, etc. issues) then I withdraw most of my criticisms.
However I still disagree with John Reiser's arguments about costs. If storage
is really slow and it's desirable to use ram instead, you have tmpfs at your
disposal. And since we're talking about systems on which the GNU C library can
be used, the idea that compressed filesystems might not be available is
unconvincing. UPX is backwards technology that makes no sense on a system with
virtual memory or any nontrivial kernel.
