You cannot - that method does not work as expected and contains an
internal bug that got fixed in Mustang b71. Check the mailing list
archives from around last December/January, there was a fairly long
discussion about this. Summary: just use cancel() on your returned Futures
- this will let the tasks drop out of the queue eventually.
