evolve: write a status message when the working directory changes

Evolve changes the working directory during atop, etc which can confuse people
as they are not aware that this happend. The ideal solution is to not have
evolve change it, however mercurial limitations don't allow us to do that at the
moment. So instead we are printing a status message that the working directory
changed.

#!/usr/bin/env python

import os, time, errno, signal

# Kill off any leftover daemon processes
try:
    fp = open(os.environ['DAEMON_PIDS'])
    for line in fp:
        try:
            pid = int(line)
        except ValueError:
            continue
        try:
            os.kill(pid, 0)
            os.kill(pid, signal.SIGTERM)
            for i in range(10):
                time.sleep(0.05)
                os.kill(pid, 0)
            os.kill(pid, signal.SIGKILL)
        except OSError, err:
            if err.errno != errno.ESRCH:
                raise
    fp.close()
except IOError:
    pass
