Running programs and their loaded libraries count as open files. Unixy filesystems don't delete open files. They change the directory entry to point to the new file and keep the old file around until it's closed. Therefore libraries are *not* yanked out from under running processes. What tends to break is badly designed GUI programs that apparently don't keep their files open but still expect different files to be from the exact same version. Firefox and Seamonkey seem to do something like that. They tend to break in funny ways when updated. Many other GUI programs have no problems with getting updated while running. Björn Persson
