A related question.<p>How can I preload a binary (for example a browser) in the background (without noticeable extra cost), so that when I start it, it opens immediately? Note that a binary may open shared-object files indirectly. It may even open data files.<p>I suppose a solution would need to run the binary while capturing system calls, so that it can learn (and predict) what files a binary will need in future invocations.
