Now USED('table') will tell you if you were succesful or not. If this seems cumbersome, try to make it a reusable method.

Just to explain this idea a bit. The only way to make sure you get exclusive use of a table is to try to USE EXCLUSIVE and then have the error handler fire if you can't get it or do as Mike suggested.
