true. What I've been thinking about (not yet implemented) is to make
some kind of 'timeout' option. When server loads are not too high files
are scanned very quick. So in such a case we could 'hold' the request
for half a second, and check again if the file is scanned already.

something like:

scannedonly: recheck_nonscanned_ms = 500

to hold 500ms and recheck the file

I can make that configurable. Something like

scannedonly: hide_nonscanned_files = False

> Write-only opens should be OK I think.

Currently write-only is always granted. Read+write needs a scanned file
and read needs a scanned file.
