+ * WARNING: DO NOT COPY THIS CODE INTO YOUR APPLICATION
+ *
+ * This code has a bug, which requires creating a separate
+ * nl80211 socket to fix:
+ * It is possible for a NL80211_CMD_NEW_SCAN_RESULTS or
+ * NL80211_CMD_SCAN_ABORTED message to be sent by the kernel
+ * before (!) we listen to it, because we only start listening
+ * after we send our scan request.
+ *
+ * Doing it the other way around has a race condition as well,
+ * if you first open the events socket you may get a notification
+ * for a previous scan.
+ *
+ * The only proper way to fix this would be to listen to events
+ * before sending the command, and for the kernel to send the
+ * scan request along with the event, so that you can match up
+ * whether the scan you requested was finished or aborted (this
+ * may result in processing a scan that another application
+ * requested, but that doesn't seem to be a problem).
+ *
+ * Alas, the kernel doesn't do that (yet).
