Gated processes the configs without dropping the BGP session.  At
least it is designed to do so and with enough physical memory to keep
the box from paging it will.  Gated is capable of digesting a new
200,000 lines configuration file and determining what it needs to do
about the differences in a minute or less.  It then takes a few
minutes to go about carrying out the changes and does so without
dropping peerings, but it really has to strain to do it if the OS has
to move pages in and out of memory to do it.
