Description Stuart Prescott 2011-03-17 01:29:06 UTC 
Recently I was experiencing very slow dns resolution (due to other problems with network-manager leaving in work dns servers in /etc/resolv.conf even though I was at home). I repeatedly saw that if I used /dns then the UI was unresponsive until the operation completed -- 5 to 10 seconds during this period of slow dns resolution.

Looks like /dns' name resolving code is currently synchronous rather than asynchronous indeed. Fixing this is going to take a bit longer than one might think because a really good fix will need some refactoring in the framework it's implemented in.

(For the record: Name resolving when making a new IRC server connection is not affected; that's done asynchronously.)

Make /dns non-blocking.
