You could do that.

However, gc_prioritise is only a reasonable thing to do with verty few blocks.
You should not have this set for many blocks at a time.

Background gc (under Linux) will also result in the blocks that were skipped
being rewritten and then a summary will be written. That is likely to take
longer, however.
