I had run first the bind-9.4.2-P1 (which throws obviuosly ignoring the
ulimit settings 'too many open file discriptors') and then the bind-9.4.3b2.
The bind-9.4.2-P1 used at a query rate around 1000queries/sec more than
700 sockets all the time (up to >980 throwing errors).
The bind-9.4.3b2 uses at the same machine under the same query load
between 200 and al little bit more than 400 sockets at a time.
Because the bind-9.4.2-P1 throws the errors after a short time (so I'd
killed it very quickly)  I can't tell about the differences on the
system load, but the bind-9.4.3b2 seems to be very nice.

best regards
