HEAD back-ldbm

back-ldbm in HEAD appears to be rather unstable at the moment, and I'm
afraid that my changes in connection management are part of the
problem. I notice that if I turn the debug level up high, test002
fails. Looking at the slapd.1.log, it appears that Add operations are
still in progress when the final ldapsearch is done to retrieve the
full database contents. This is really puzzling, it means that the
ldapadd command exited successfully already, but the operations it
submitted hadn't completed yet. With lower debug levels, the Adds
complete quickly enough to finish before the ldapsearch finishes.
Otherwise, one to three entries from the tail of the Add are missing
from the search result.
This also seems to be causing test008 to fail. Also in test008, there
is garbage text appearing in the LDAP error text fields. I don't know
what it's leftover from...
The big problem here seems to be that back-ldbm calls
send_ldap_result() to tell the client its status before it actually
finishes its internal operations. So it can be in the middle of
completing a cache update by the time a new request arrives; this
seems to explain what I'm seeing in test002 at least.
Looking more closely at the logs, there appears to be a bug in with
ldbm_back_referral and most likely in bdb_referral as well. A referral
is being sent for every Add operation because the target of the op
(naturally) doesn't exist. Something is very screwy here.
