It's a good fix. I added that case to the code after reading a comment
from Carmack that indicated that leaving the second TMU active, even if
it wasn't used, could be a serious performance hit. Of course, if you
only have one TMU, making that call is bad news. Thanks for the
patch. It should definetly go in. I think it'll help a few of the
Banshee users as well.
