Indeed. For extra fun, try watching your "show route forwarding-table 
summary" after you reboot, and see how long it takes for your router to 
actually get a full table installed. The more BGP load you have on the 
device, the more you'll see that it totally stalls the installation of 
routes into the FIB. At this point I can't describe it as anything less 
than a major architectural flaw which Juniper is completely powerless to 
fix.
