#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.

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

  shutting down cleanly

  press ^C again to terminate immediately (dangerous)

  end of unsafe operation

  interrupted!
