You asked for several things:

This is not reasonable to ask a single developer to do.

> 2) Retains m:n support for uniprocessor as an option

This is an unrelated feature request. Given the reasons around
switching from M:N to 1:1, I think the burden of making this work
should be on the people who want it, not the people who want 1:1. I
wrote the M:N support, and I'm not even bothered enough to keep it

> 3) a reasonable amount of pthread testing

This is more reasonable, but again I think that it's just out of scope
for one developer. That doesn't mean that that one developer shouldn't
introduce the change; it means that the developer should help move
things along as problems are reported. From what I've seen, that's
what's happening.

This assumes that -current needs to work all the time. I'll repeat
this: I don't agree. This is *exactly* what -current is for. Again, if
this bothers you, wait for a release.
