According to related postings on the OpenLDAP lists libldap_r is re-entrant 
on a per-connection basis. Therefore linking with libldap_r improves the 
situation since a finer-grained locking is used in LDAPObject class (see 
method _ldap_lock()).

Note that proper support for libldap_r also depends on the version of the 
OpenLDAP libs used.
