I have now improved that as follows:

faster check for non-repository, especially relevant for find_repository
to avoid repeated invocation of "hg root";


A more profound approach to speed up repeated document builds works via
Isabelle/jEdit and the Console/Scala plugin.

The invocation of "isabelle build" within that already running Scala/JVM
environment works like this:

  Build.build(PIDE.options.value, new Console_Progress, select_dirs =
List(Path.explode("~/Slides/Curry-Club_Aug-2017")))

The second, third, ... run will be much faster.


That direct use of the Scala function also bypasses the repository
check, because check_unknown_files = false by default.
