When propagating a search to multiple subordinate databases, and a timelimit is
in effect, backglue decrements the timelimit after each subordinate search, to
account for the time spent so far. However it needs to also increment the
op->o_time accordingly, otherwise all of the invoked backends will calculate
their stoptime's incorrectly, resulting in a search aborting after only half of
the specified timelimit has passed.
Thix is fixed in CVS slapd/backglue.c 1.113 -> 1.114
