This is like old times, when everyone that wanted to sell down at whatever price it was at had done so, and there was no one else wanting to, or having to, sell so low. It would go for hours without a trade, just like Blue mentioned with the siesta.
Even those that may have a few shares to sell so try and drop the price are hesitant to do so. This use to happen on a fairly regular basis. A rise in the pps would typically follow such inactivity.
