One of the problem with operating system updates is that you often need to reboot the system. While this is nothing but a minor nuisance for us desktop users, it's a bigger problem when it comes to servers. Ksplice is a technology that allows Linux kernel patches to be applied without actually restarting the kernel.

There must be a fundamental difference in how files are handled in Windows and *nix. On a *nix system, when a process reads or writes a file, and this file is deleted, renamed or replaced by another process, the first process will still see the old file until it closes its file handle.
I trust that loading libraries works the same way, although I don't know the details. I guess the trick is that files are considered the same if they are the same inode, regardless of where or when you found them in the file system tree.
