It would appear that every few seconds, Xcode decides to create some monster XML document that hangs the main thread for several seconds. There is usually a garbage collection thread that's running at the same time, which also might be slowing down the main thread as I find lots of sample stack fragments like this:

That GC is busy just means that there is a ton of allocation activity going on.   The sample from the main thread indicates that there is a ton of ongoing object archival occurring.

Is project particular large?  Has a lot of files?

In any case, file a bug and attach the samples.
