It is common to run trac under non-privileged user without home directory. In this case `trac-admin . deploy
stuff` hangs with the following error message and doesn't even respond to Ctrl-C/Ctrl-Break. So the only way is
to send it to background with Ctrl-Z and then kill it with some other means.

$ trac-admin . deploy jtest

pkg_resources.ExtractionError: Can't extract file(s) to egg cache

The following error occurred while trying to extract file(s) to the Python egg
cache:

  [Errno 13] Permission denied: '/home/trac'

The Python egg cache directory is currently set to:

  /home/trac/.python-eggs

Perhaps your account does not have write access to this directory?  You can
change the cache directory by setting the PYTHON_EGG_CACHE environment
variable to point to an accessible directory.
