#require no-windows no-rhg
XXX-RHG this test hangs if `hg` is really `rhg`. This was hidden by the use of
`alias hg=rhg` by run-tests.py. With such alias removed, this test is revealed
buggy. This need to be resolved sooner than later.
Dummy extension simulating unsafe long running command

Kludge to emulate timeout(1) which is not generally available.

shutting down cleanly
press ^C again to terminate immediately (dangerous)
