Appears to me that unless timelimit value passed to ldap_search_ext() is
positive, the ld_timelimit from .ldaprc overrides, so there's no way for
syncrepl ldap_sync_search() to literally specify "unlimited".

To duplicate: configure syncrepl timelimit=unlimited;  edit /.ldaprc ->
"TIMELIMIT 23"; start replica slapd with a sufficiently large replication
backlog; observe timeout at 23 seconds.

To kludge:  use extravagantly large value instead:  if (si->si_tlimit > 0)
timeout.tv_sec = si->tlimit; else timeout.tv_sec = 31536000;

and pass &timeout unconditionally.
