I'm thinking he best place to import it is as a replacement for libthr,
since that's the closest architecturally (libthr was also 1:1,
synchronization based on umtx, etc).  However, we should ping jeff and mtm
to make sure they don't object. 

Another reason not to drop it over libpthread is that it keeps libpthread
around for direct comparison (performance, etc), and also means that the
production thread library from 5.x is still in 6.x, so gives a better path
for testing and merging of fixes.
