You don't have any guarantees that running process won't try to use stuff from disk later on do you? If it segfaults (and it does in my "general usecases") it's hard to debug - you got nothing conveniently on disk. And no, "upgrading libc" is not a general usecase, it's just one of those few things that work because they were written in a very specific way, and you should not apply that technique in the general usecase. If you want, I can provide you some reproducers but lets not continue this "but, seriously, it works fine for me" kind of discussion. Thanks, -- Ionel Cristian Mărieș, http://blog.ionelmc.ro
