Okay guys, Murphy never sleeps, and I managed to inadvertently break the symbolic names (MT_NICE_FILTER, MT_MULTI_INSTANCE, MT_SERIALIZED) of the MT modes last minute before release. So if you used these names with r1778, they didn't work correctly. I just published r1779 which corrects this fuckup of mine. Please be sure to
pull r1779 if you are experimenting with MT, because this fix is kind of
vital for it.
