Hmmm. I guess this is a consequence of changing the timeout 
representation in the LDAP handle. I suppose we can just make the 
syncrepl consumer do an explicit ldap_set_option() on its session 
handles to override any .ldaprc setting. Will have to play with this a 
bit to see how we can maintain backward compatibility.
