  Looks very cool... simple unix-style API!

  A related question. 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. 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.

    Try preload (https://wiki.archlinux.org/index.php/Preload#Preload https://wiki.archlinux.org/index.php/Preload#Preload) or maybe e4rat (https://wiki.archlinux.org/index.php/e4rat https://wiki.archlinux.org/index.php/e4rat).

  I've been using this for a few years to cache basically the whole of a USB drive after booting from it. It helps make up for the slow read speed of many cheap flash drives by caching everything before a user even sits down to use it.(I run a programming contest so we set the computers up and boot them before hand, plenty of time for vmtouch to do its job)
