Cause an error that brings up a debugger screen in X. Hit `p' to choose a restart. Hit `C-g' to abort the choice. I observe some flickering of screens and then a new debugger screen presenting the error:

;The object 2, passed as the first argument to xterm-map-y-size, is not in the correct range.

Re-evaluating the call to XTERM-MAP-Y-SIZE in one of the debugger's REPLs yields the expected numeric result, so the editor's X terminals appear to be briefly desynchronized from the microcode's. This is reproducible enough that it may not even be a race condition so much as merely disordered event processing somewhere.
