Yep, that's a good idea. Thanks.

Unfortunately, num_sources has nothing to do with supported vector space,
and it would really have to be num_sources+7, this possibly overrunning
the available range, hardware-wise (instead of just losing the topmost
sources to the software uses).

I'll repost the patch with the change above together with the rest of
the series.
