Re: RE24 connection code reworking
Since test008 worked nicely overnight I decided to get a bit more
aggressive. I don't think it's related to connection code, but with HEAD
(large batch of ADDs; local smoke tests, not from ldap-src tests):
t@16 (l@16) terminated by signal SEGV (no mapping at the fault address)

db4 4.7.25 patched for Oracle #16406, #16415, and #16541. All other slapd
threads are idle. FWIW, I'm not fully patched for #5860 (will re-checkout
now, and kill the optimization on libdb4-7).
