And yet another approach is simply to bump up each lconn's refcnt, the same way request.c:ldap_new_connection() does, to prevent them from getting freed prematurely. This latter approach would be simplest, except it requires calling ldap_free_connection() to actually decrement the refcnt, and that requires more mutex manipulation for the libldap_r version. (I haven't looked too deeply into the lock dependencies yet, it may actually be simpler.)

I opted for this approach, now checked into HEAD. Please test.
