It is indeed much faster now, but is broken here (with the attached
defconfig):
    $ ../br.package-create-users/support/scripts/graph-depends 
    Getting targets
    Getting dependencies for ['argp-standalone', 'avahi', 'busybox',
    'cifs-utils', 'connman', 'dbus', 'dropbear', 'expat', 'gmp', 'gnutls',

Does it require a specific Python version? Mine is:
    $ python --version
    Python 2.6.6

git bisect gives as culprit:

Bisecting: 0 revisions left to test after this (roughly 0 steps)
[4359685e145798f06d88eb2e5ba5979ba5de882e] graph-depends: optimize execution
speed

I'll try to look at it tonight...
