Multiple Kernel Tables on one BIRD Table

[Matt Corallo]

When trying to sync a BIRD routing table to multiple kernel routing tables (with different export filters, obviously),
BIRD refuses with, eg, "Kernel syncer (v6kern) already attached to table master6". Is this something that is fundamental
or would be it easy to address this by allowing it if the "kernel table" field has a different value?

Thanks,
Matt
