That would only happen with an outrageously over-subscribed provider.

OK - I'll feed the troll.  What's the proper amount of unused and therefor
non-revenue-generating capacity the operator is supposed to reserve in order to
*guarantee* that bandwidth will be available?

(Hint - the provider doesn't have to be "outrageously" oversubscribed - by
definition, if you're oversubscribed *at all*, it's possible for somebody to
lose out.  It's easy for the provider to be 98% sure that they'll be able to
satisfy all the requests.  But guaranteeing 100% is a whole nother story...)
