-# directories.  Directories not in use are removed.  Old versioned directories
-# that are in use are left alone so as to not interfere with running
-# processes.  These directories can be cleaned up by this script on future
-# updates.
-#
-# To determine which directories are in use, both ps and lsof are used.  Each
-# approach has limitations.
-#
-# The ps check looks for processes within the verisoned directory.  Only
-# helper processes, such as renderers, are within the versioned directory.
-# Browser processes are not, so the ps check will not find them, and will
-# assume that a versioned directory is not in use if a browser is open without
-# any windows.  The ps mechanism can also only detect processes running on the
-# system that is performing the update.  If network shares are involved, all
-# bets are off.
-#
-# The lsof check looks to see what processes have the framework dylib open.
-# Browser processes will have their versioned framework dylib open, so this
-# check is able to catch browsers even if there are no associated helper
-# processes.  Like the ps check, the lsof check is limited to processes on
-# the system that is performing the update.  Finally, unless running as root,
-# the lsof check can only find processes running as the effective user
-# performing the update.
-#
-# These limitations are motiviations to additionally preserve the versioned
-# directory corresponding to the version that was just replaced.

-# below is not expected to expand to nothing, but nullglob will prevent the
-# loop from trying to remove nonexistent directories by weird names with
