Delay between Scanning and Listing Access Points

Funny to see the people at Placelab stumbling on the same problems as me. From their mailing-list:

Originally, our xp spotter sends the scan command to the NDIS driver, than it immediately queries the driver for the bssid list. However the scanning happens at background and the scan function returns immediately (or asychronously). As a result, the bssids returned is in fact for the second to the last scanning. EX: If we are scanning at 2 second interval, the bssids returned were 2 second old. A quick fix is to simply wait certain time after the scan command. MSDN suggest 6 seconds, but I use 300 ms based on the Linux spotter setting.
