doesn't matter that much. after a program started and got loaded into
memory completely solaris releases the lock on that file. next time you
start it after copying something over it it runs the new version while the
old might still be running.

under linux it usually works the same way.
one exception are programs that try to load something from the same file
while running. those get a rough end if the file changed meanwhile.
bad times when this happens to essential system processes ;-)
