    * HttpApplicationFactory.cs: watch for changes to web.config also
    in the subdirectories.

The result is that, at least with Inotify, it creates a watcher on every
subdirectory of the app path (three times?), and this involves scanning all of
the subdirectories. My app path has a LOT of data files in a deep directory
structure, and this causes the app initialization to take a very very long
time.

Putting these three lines back fixes the problem.

Perhaps this is a bug with the Inotify FileSystemWatcher?
