I was just checking because alpha hardware is quite antique, it's single-core
so a full compile with bootstrap takes around ~72 hours.  I don't know how long
the test suite takes because I've never run it on this machine, but I would
expect it to add a couple additional days to that.  If that's fine I'll kick it
off, just want to be clear on what exactly you'd like to see.
