Autoscan hangs for large directories

[ByteSyze]

Knowledge becomes unresponsive and eventually halts when the autoscan folder contains many files. I suspect this should be a consideration for #33 as it would likely leverage similar routines.

I don't know enough about how autoscan works to propose a solution yet.

Steps to recreate:

1. Set the autoscan directory to a folder containing many files (e.g. Knowledge source folder)
2. Wait for autoscan to occur
3. ???
4. Profit
