--------------------------------------------

Earwin, that sounds great (changing current API instead of new IW method), I think?  Can you
open a new issue?  Thanks.

> Now that LogMP can do non-contiguous merges, the fact that it disregards which segments
are already being merged is more problematic since it could result in it returning conflicting
merges and thus failing to run multiple merges concurrently.
