??? auto-revert-mode periodically checks all buffers that are visiting
a file.  The frequency of these checks is determined by the variable
auto-revert-interval, by default every 5 seconds.

Perhaps you need to set auto-revert-stop-on-user-input to nil and
maybe also play with auto-revert-interval's value, to get almost
instanteneous automatic reverts whenever a file changes.

Perhaps a feature can be added to autorevert.el, whereby it checks the
buffers when a focus event arrives.  All the rest is already there, I
believe.
