I wonder if this depends on the format(s) of the recently opened. For example, if the first four recently opened are PDFs, but the fifth is epub, then the epub seems to open without the "Please wait" pop-up. So, maybe the device can hold up to four documents of each format in whatever this background memory is.
Also, rebooting seems to clear this background memory. Whilst your recently opened list will still be there on rebooting, it takes longer for the device to open even those at the top of the list, and you get the "Please wait" pop-up-
So, maybe rebooting before putting to stand-by may lengthen battery life by clearing this supposed background memory. It might also be an argument for implementing an optional "off" state which would also clear this memory.
