  4.9.* works just fine with more than 256 interfaces.  There is a compile
time constant you have to tweak.

  FreeBSD by default has a constant (it's in one of the header files)
that limits to 256 file descriptors.  If you compile bind with a larger
descriptor it works fine.

  Took me a few hours to track that one down in the debugger.  One of
our clients has a lot of scripts that depends on 4.9's config. file syntax
so 8.x wasn't an option at the time.
