New Revision: 17817

Modified:
   trunk/Open-ILS/web/js/ui/default/circ/selfcheck/selfcheck.js
Log:
for large sets of holds, usually around 10 or more, the holds display takes a little too long.  instead of collecting them all and sorting them by queue position, slot them into the display table (by queue position) as they arrive
