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

    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*
