You mean esd* is a hack.

(0) Reinvent the wheel.  There were at least three adequate sound
daemon architectures (rplay, Xaudio, and NAS) available, but the esd
developers had to invent a (not very interesting) new one and then
implement it badly.

(1) (This is long fixed, but typical.)  Spam the kernel with literally
hundreds of interrupts per second.

(2) Hook interrupts incorrectly, creating race conditions.

(3) libesd hooks SIGUSR1, which should be left for the app's use.
Furthermore, see (2).  Worst of all, it's the third level of
redundancy in lib <-> daemon communication, used to attempt to wake up
the daemon if it's wedged.  (It's not your machine, it's ESD's.)

(4) The fourth level of redundancy is that if libesd can't find any
other way to talk to a daemon, it forks one off itself, in polling
mode.
