      git patch file (master) -- need to
        close a small window for a pr index competed among multiple
        threads

        Without closing this window, the async requests accepted via the
        same connection compete one pr_idx:

        conn=1214 op=73 SRCH
          base="cn=accounts,dc=testrelm,dc=test" scope=2
          filter="(&(|(memberOf=ipaUniqueID=338799a0-ee18-11e4-9e0c-00215e2032c0,cn=ng,cn=alt,dc=testrelm,dc=test))(objectClass=ipaHost))"


          attrs="objectClass cn fqdn serverHostName memberOf
          ipaSshPubKey ipaUniqueID"

          conn=1214 op=74 SRCH base="cn=accounts,dc=testrelm,dc=test"
          scope=2
          filter="(&(|(memberOf=ipaUniqueID=37040000-ee18-11e4-8c14-00215e2032c0,cn=ng,cn=alt,dc=testrelm,dc=test))(objectClass=ipaHost))"


          attrs="objectClass cn fqdn serverHostName memberOf
          ipaSshPubKey ipaUniqueID"

          conn=1214 op=75 SRCH base="cn=accounts,dc=testrelm,dc=test"
          scope=2
          filter="(&(|(memberOf=ipaUniqueID=3036b6a0-ee18-11e4-b7dd-00215e2032c0,cn=ng,cn=alt,dc=testrelm,dc=test))(objectClass=ipaHost))"


          attrs="objectClass cn fqdn serverHostName memberOf
          ipaSshPubKey ipaUniqueID"

          conn=1214 op=73 RESULT err=0 tag=101 nentries=200 etime=0
          notes=P pr_idx=1

          conn=1214 op=75 RESULT err=0 tag=101 nentries=200 etime=0
          notes=P pr_idx=1

          conn=1214 op=74 RESULT err=0 tag=101 nentries=200 etime=0
          notes=P pr_idx=1

        
        It is solved as follows:

        conn=14 op=15 SRCH
          base="cn=accounts,dc=testrelm,dc=test" scope=2
          filter="(&(|(memberOf=ipaUniqueID=338799a0-ee18-11e4-9e0c-00215e2032c0,cn=ng,cn=alt,dc=testrelm,dc=test))(objectClass=ipaHost))"

          attrs="objectClass cn fqdn serverHostName memberOf
          ipaSshPubKey ipaUniqueID"

          _onn_=14 op=16 SRCH base="cn=accounts,dc=testrelm,dc=test"
          scope=2
          filter="(&(|(memberOf=ipaUniqueID=3036b6a0-ee18-11e4-b7dd-00215e2032c0,cn=ng,cn=alt,dc=testrelm,dc=test))(objectClass=ipaHost))"

          attrs="objectClass cn fqdn serverHostName memberOf
          ipaSshPubKey ipaUniqueID"

          [01/May/2015:13:07:59 -0400] conn=14 op=17 SRCH
          base="cn=accounts,dc=testrelm,dc=test" scope=2
          filter="(&(|(memberOf=ipaUniqueID=37040000-ee18-11e4-8c14-00215e2032c0,cn=ng,cn=alt,dc=testrelm,dc=test))(objectClass=ipaHost))"

          attrs="objectClass cn fqdn serverHostName memberOf
          ipaSshPubKey ipaUniqueID"

          conn=14 op=15 RESULT err=0 tag=101 nentries=200 etime=0
          notes=P pr_idx=1

          conn=14 op=16 RESULT err=0 tag=101 nentries=200 etime=0
          notes=P pr_idx=2

          conn=14 op=17 RESULT err=0 tag=101 nentries=200 etime=0
          notes=P pr_idx=0
