the code in the ALSA backend suffers from terrible jitter because of
incorrect design.

the a2jmidi codebase is the only thing that gets this right;
ironically, in its original incarnation, it had 3 executables (j2a,
a2j and a2jmidid), and only the two simple ones got the design right.
a couple of years i worked on fixing up a2jmidid so that it now has
zero jitter (constant 1 period latency).

eventually the plan is to rip the existing ALSA backend code out, and
replace it with something like an internal JACK client based on
a2jmidid.
