I tracked them +down to some of the Xlib function calls in my stripchart code (yes, I wrote my +own +[stripchart](http://www.physics.drexel.edu/~wking/rsrch/code/index.shtml#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. + +[[!tag programming]] -- 2.26.2
