inotify: process all inotify events in one batch
When several inotify events happen, we don't have to process each event
separately, calling everytime repowatcher.read_events() to fetch events from
the underlying watcher: it is sufficient to call once read_events, to fetch
all the events from the watcher.
#!/bin/sh
hg init a
hg clone a b
cd a
echo '[paths]' >> .hg/hgrc
echo 'dupe = ../b' >> .hg/hgrc
hg in dupe | fgrep '../'
cd ..
hg -R a in dupe | fgrep '../'
