In case someone even thinks of ever doing that, please note:

rtr(config)# router ospf 10
rtr(config-rtr)# redistribute bgp 65000 subnets route-map
JustATeensyFiftyRoutesOrSo

certainly does works as advertised (no idea if it consumes a lot of
CPU to filter out all those routes) . . . but trying to remove that
using

rtr(config-rtr)# no redistribute bgp 65000 subnets route-map
JustATeensyFiftyRoutesOrSo

results in

   redistribute bgp 65000 subnets

and that *hurts*
