An old problem, and one reason why some other OSs *needed* occasional
reboots, after a while.  Even quitting all running applications, back
down to just having the basic desktop, and deliberately issuing flush
commands, wasn't enough to free up all the RAM.  Particularly when
something needed a big contiguous block, because some (later than boot
time ran) system things might be sitting in the middle of the RAM.
