Well every router that carries to global bgp table will have those routes
removed, and then have those routes re-added when your bgp peer session
comes back up.

Well, just don't do it :). Seriously, unless you have too. If you just
need to clear a single peer, then clear ip bgp x.x.x.x . Also you can run
"soft reconfig" with your peers so that when changes are made, effects to
the routers can be minimalized. Running "soft reconfig" requires you to
keep an additional copy of the BGP table, and when you run multiple peers
this can add up.............but if you have the memory, its a good idea.
