test039 sporadically locks up when running on Solaris 10.  It took my system
some 150 or so passes to trigger.  On another system, it took only 16, so YMMV.

What I see from the logs in the testrun is that slapd.3.log sends a response,
and then halts:

58a723cf <<< dnPrettyNormal: <cn=All Staff,ou=Groups,o=Example,c=US>, <cn=all
staff,ou=groups,o=example,c=us>
58a723cf => send_search_entry: conn 1003 dn="cn=Bjorn Jensen,ou=Information
Technology Division,ou=People,o=Example,c=US"

slapd.2.log shows that the last thing it did was send a result, and then all the
open connections to it from slapd-mtester timed out:

58a723cf send_ldap_result: conn=1008 op=15 p=3
58a723cf send_ldap_result: r=3D0 matched="" text=""
58a723cf send_ldap_response: msgid=16 tag=101 err=0
ber_flush2: 14 bytes to sd 24
58a723cf conn=1008 op=15 SEARCH RESULT tag=101 err=0 duration=0.298ms nentries=0

58a723d5 conn=1003 fd=19 closed (idletimeout)
58a723d5 connection_close: conn=1004 sd=20

(etc)

slapd.1.log Also shows the last thing it did was return a result:

58a723cf bdb_search_candidates: id=1 first=9 last=9
58a723cf => send_search_entry: conn 1005 dn="cn=Bjorn Jensen,ou=Information

58a723cf <= send_search_entry: conn 1005 exit.
