I was thinking the same thing.  We have a whole bunch of relatively low-
risk patches stacked up in git, might as well call them 2.73.

I'd like to see some broad testing first, though.  What if I put out an
alpha release sometime this week and distribution maintainers do some
mass rebuilds with it?  Also, does anyone know of any high-importance
patches waiting for review, or other high-importance bugs that should be
addressed ASAP?

p.s. Paul, you're just as entitled to turn the release crank as I am :-)
