Further testing with Andrew's kvm image shows the hang only occurs when Cyrus 
SASL's libsasldb2.so plugin is present. I always remove that plugin from my 
installs, since I only use in-directory SASL secrets. That's probably why I 
wasn't seeing the reported behavior before.

Also a note - it's still not clear we've been talking about the same thing up 
to this point. Even when the samba test suite hangs, I see that ldapsearch 
still works fine against slapd. At any rate, currently all of the samba4 tests 
pass for me.
