I was trying to troubleshoot the feedback loop on our NanoScope today,
and when I went to fire up my [[Comedi]]-driven stripcharts monitoring
some lines in the DB-25 cable connecting the [[MultiMode]] to the
Nanoscope, I got a bunch of weird errors (errnos 11 and 29).  I
tracked them down to some of the Xlib function calls in my stripchart
code (yes, I wrote my own stripchart code, so sue me), which I don't
understand, since I can't find any reference to Xlib functions setting
errnos.

Anyhow, I've patched up my source to gleefully ignore any Xlib errno
settings, and things seem to be back up and running now.  Feel free to
give my stripchart code a whirl, since I quite enjoy it :p.
