Out of the PRs we have, two are actually fixed but not marked as such. 
This year's PRs are from the recent Zdenek's Debian rebuild with GCC 6 and 
I will be on them now.  For the other two last year PRs, it is my fault not 
to fix them in a timely manner.  Frankly, 2015 was very tough for me and my 
colleagues (we worked 6 days a week most part of the year), but since 
January it is fine again and we'll catch up now.  Sorry for that.

You're also right that sel-sched now gets limited testing.  We're made it 
work initially for ia64, x64, ppc and cell, and then added ARM, too. 
Outside of ia64 world, I had private reports of sel-sched being used for 
cell with success, and we used it in our own contractor work for optimizing 
some ARM apps with GCC.

In short, we're willing to maintain sel-sched and I apologize for the slow 
PR fixing speed last year, it should be no problem anymore as of now.  If 
there are any big plans of reorganizing schedulers and sel-sched stands in 
the way of those, let's discuss it and we'll be willing to help in any way.
