After some time away from the Dashquit item, I was able to download another copy
from the link I posted above (even though the built-in Dashboard app was unable to
find the same one the official link goes to) and get an OK'd download that does work
of the 2008 widget named Dashquit_3.0 and it interrupts the dashboard & resets it.
Not sure what else it does, but apparently some caches are emptied that affect the
Finder window & other user interface items, at least in my Mac's Mavericks 10.9.5...
As a result, application and interface items load a little faster, windows too. I could
not tell if a noticeable amount of RAM was freed-up, or what was affected. There
were no adverse effects from its use. And it may not work in El Capitan. Some of
the return of faster interface experienced after Dashquit 'quit the Dashboard' may
be similar to a full restart of the computer if it hasn't been done in awhile. {I mention
this because my Macs may go a month or two without a restart; given UPS battery
power backup units and power filters that are in place. In winter, grid outages can
force me to shut down the computers.} In past decades, I had a backup generator
to keep my macs and house energized; but no generator is present in this location.
There may be a command-line method or an interface utility method to attempt reset
or to shut down the Dashboard; maybe a tool in OnyX (titanium software) may do it.

My older Mac OS X versions have been used with OnyX, but not the newer ones;
as there are various items that may be adversely affected by using that utility.
If nothing else, I guess to not bother with Dashboard or widgets may do as much! 🙂
