[ANN] Rainbows! 4.1.0 - minor internal cleanups

[Eric Wong]

Changes:

There are only some minor cleanups in this release and a bump to
kgio 2.5 to remove the dependency on io/wait.  kgio 2.5 or later
is now required (kgio 2.6+ will be required in the next
release).

I don't recall hearing of anybody running Rainbows! in production
and serving public traffic, yet.  You can be the first!  Have fun!
