Comment (by dd32):

 The major problem is that there are no tests in that file which test
 hierarchical taxonomies, and as a result, none touch on the `exclude_tree`
 parameter.
 There's a good reason for it, our hierarchical terms caches are a bit of a
 mess, you can't reliably create, and query a hierarchical term on the same
 request, even when using the cache cleaning API..

 [attachment:25710.diff] is a basic unit test and patch that appears to fix
 this for me.
