they are (relatively) expensive and should be unnecessary now:
we have blur, it works well, and when we don't blur we use different backgrounds.
one more "take one thing off" while i'm futzing around in tooltips
the previous fix, which i accidentally reverted while cleaning up this code,
was actually wrong (so in a way i'm glad i caught it): the signal MUST be emitted
AFTER the item is removed from the collection otherwise any code that checks to
see if that source exists will see that it does still exist even though it was
just signaled as being removed. order sometimes really matters :)

BUG:287795
loadRunners intelligently only unloads those runners with are no longer to be loaded, so this is a performance win.
it now also checks to see if there are pending jobs for the runners to be deleted (if any) and if so it creates a delayed
deleter for them -> no crashes
from the "useful things missing from bug reports" and "wondering wtf is wrong with people
while trying to get the useful bits out of a bug report" files ...
