Throttling is not necessary in a stable network because a candidate
BSR does not generate any BSMs as long as it receives those from the
elected BSR (i.e. this particular event does not occur at all in this
case).  Thrashing during BSR (re-)election is prevented by
BS_Rand_Override, so this issue appears to be moot.
