+Subject: [PATCH] Add a dptr to Cache, and move the throttle timer there to fix
+ crash
+
+Previously, the throttle timer was a raw static, but it was also a parented 
qobject, which means that when the cache was deleted, so was the timer, but the 
variable was not reset. Consequently, things would crash left and right later 
on. So, to alleviate this, and hopefully avoid future issues, introduce a dptr, 
stick the timer there, and move the logic to that private class as well.
