inotify: Separate query sending logic from Server starting.

Use a decorator around the public statusquery method of Client:

start_server(query_to_server):
    try:
        query_to_server()
    except QueryFailed:
        [error recovery, inotify Server (re)starting]
        query_to_server()

This way, introducing a new xxxquery Client method is easy:
one has only to code the protocol part of xxxquery, ignoring errors,
and decorating it using start_server to handle server recovery
and (re)starts

#!/bin/sh
#
# Corrupt an hg repo with a pull started during an aborted commit
#

# Create two repos, so that one of them can pull from the other one.
hg init source
cd source
touch foo
hg add foo
hg ci -m 'add foo'
hg clone . ../corrupted
echo >> foo
hg ci -m 'change foo'

# Add a hook to wait 5 seconds and then abort the commit
cd ../corrupted
echo '[hooks]' >> .hg/hgrc
echo 'pretxncommit = sleep 5; exit 1' >> .hg/hgrc

# start a commit...
touch bar
hg add bar
hg ci -m 'add bar' &

# ... and start a pull while the commit is still running
sleep 1
hg pull ../source 2>/dev/null

# see what happened
wait
hg verify
