Wow, that's far more than I expected!  Good to know.  :)

I don't have perlbal serving any static resources yet. Since only some

Linux::AIO is the predecessor to IO::AIO.  The former used to be what worked
reliably while the latter was maturing, but now that it's mature, there's no
reason to use anything other than IO::AIO.
