hmm. I looked at this a little over the weekend and I never could
determine an easy way to see both ends of the socket. Obviously, you can
determine with netstat the process that owns the socket, but figuring
out which client process links to it is difficult without debugging
either with strace, or gdb. That's more of a hassle than I wanted to
deal with.

Anyway, the easiest way I found to see what processes are hooked into
esd was using "lsof |grep esd". At least, you can see what processes
utilize esd, and the number of links to esd's socket is roughly the same
number of those processes listed. It should be good enough for a
ballpark estimate.
