Chrome and Android have both forked() warmed-up processes to speed application startup. Although looking at this 2011 post it's more complicated than I thought in Chrome: http://neugierig.org/software/chromium/notes/2011/08/zygote.html http://neugierig.org/software/chromium/notes/2011/08/zygote.... This one is also kind of old: http://coltf.blogspot.com/p/android-os-processes-and-zygote.html http://coltf.blogspot.com/p/android-os-processes-and-zygote.... If anyone has any updates on these I'd be interested. As far as I remember App Engine also did a similar thing to avoid reinitializing a Python VM for every request.
