actually that was unnecessary. I was able to reproduce this using
either strace or xtrace to slow things down. The underlying issue
is an obliquely-documented(*) misfeature of the X11 library, for which
I can make a suitable workaround.
(*) I'd say "undocumented", but someone who reads the source code would
argue that someone could _guess_ from the manual page what the code
is actually doing :-)
