Comment(by quozl):

 Any instantiation of BundleRegistry() causes filesystem I/O and the setup
 of a change notifier for the Activities directory.  The cost is 905ms
 tested on OLPC XO-1.5.  Use of the D-Bus API ensures that no additional
 filesystem I/O is required, since the shell is queried directly.  Those
 other uses of BundleRegistry() presumably suffer from the same delay.  I
 question the value of just using the patch code directly in sugar-launch.
