Scanning results take a long time to return back to users
Is this the fault of the scan cache? There are DEFINITELY some good ways to optimize this and make it more efficient... but why aren't they working?
Not sure if this is relevant, but something I noticed was that it seems to request a scan of the same channels over and over, as if the OS doesn't retrieve them correctly the first few times:

(filtered console output, there are a lot of lines that have been omitted between each set of 6)
I’ve tried to take a stab at this again with more scan cache optimizations, but we have a problem where wireless networks tend to disappear..
