"resource temporarily unavailable" I believe means -EAGAIN, which means the card is currently scanning. However, ideally that shouldn't stop the driver from returning the previous scan results to you (as long as they aren't too old of course, at which point they should be culled). If a program wants the latest results, it can certainly listen for the netlink messages the driver sends when it has updated results. I think this requires a driver update; maybe wpa_supplicant needs to be more lenient in its timeouts for getting scan data out of the card, but I'm pretty sure it's waiting ~ 10s max before asking the card for results explicitly.
