Sorry for taking forever to wrap my brain around this, I think your
patch is the way to go and I will merge it.

The code was trying to match the allowed port range with the sizing
of the bind hash table, which is hashed by local port number.  But
even considering that I think it's OK to use the full range by
default, always.

Thanks a lot.
