I'm willing to accept there are cases you can not recover, and
the only acceptable alternative is to reboot (gee, Microsoft thinks
that is the solution to everything).  My objection is RFC 1771 does
not give implementations the ability to continue when they can.

Aborting the BGP session should be an option, and extreme option,
but not the ONLY option.  So should throwing away the bad data,
alerting, and continuing with good data.
