Bryan Boreham ab3a47b489 postings: use Loser Tree for merge It's faster. Note change to test - instead of requiring that the data structure is identical to `EmptyPostings()`, check that calling `Next()` returns false, which implies it was empty. Also the check for context cancellation during initialization was removed. Initialization should be a small portion of the work done during merge, so it's not worth plumbing a context argument through. Signed-off-by: Bryan Boreham <bjboreham@gmail.com>		12 months ago
