Bind 9 unexpected behaviour

Hi,
I'm testing Bind9.0.0 for use in a large production environment
(150,000+ domains) and have come across a few oddities.
1) named doing a fatal exit when coming across any sort of problem in
named.conf I can sort of live with (although it would nice to have a
toggle to turn that behaviour off) but when there's any sort of zone
syntax error it also dies on the initial load (not documented that I can
find). This is really annoying when I've got many many domains being
edited by users - sometimes mistakes are made.
2) I often get this sort of error when doing an initial load:
Sep 29 17:01:01 mercury named[23149]: com/zonefile: open: unexpected
error
Sep 29 17:01:01 mercury named[23149]: dns_zone_load: zone
zonefile.com/IN: dns_journal_rollforward returned: unexpected error
Sep 29 17:01:01 mercury named[23149]: loading zones: unexpected error
Sep 29 17:01:01 mercury named[23149]: exiting (due to fatal error)
If I hit the up arrow and start it again, it will be OK (sometimes I'll
get the error a second time and have to restart a third time).
I'm starting with /path/to/named -n 2
3) I'm trying out the rndc. It claims the reload command is
implemented, but when I try and 'rndc reload domain.tld' it gives two
separate success lines for reload and domain.tld. Will bind9 rndc allow
reloads of a single domainname? It's very useful for me to reload a
single domain rather than 150,000!!!
'part from that, bind9 looks like a really big improvement - it's
certainly a lot faster and it's nice not having to wait for named to
load named.conf, load all the zone files **and** then send out all of
it's notifies before it bothers responding to queries...
My system is: RedHat Linux 6.1, 2xCPU, 1/2Gb, Bind9.0.0release

ps - is there the same limitation as bind8 where the entire named
process must reside in physical ram and not swap out? if so, how do I
stop it swapping out? Bind8 used to use 750+Mb, Bind9 uses about 350+Mb
so is better but still hammers my machine!!
