The issue is that Xserver default behaviour is to restart after the
last client disconnects.  Apparenlty there's a race between xinit
detecting that xinitrc exited and killing the server and the server
detecting last client (xinit!) disconnecting and initiating reset.

When xinit finally kills the server the server has already reopened
the keyboard in raw mode.  I haven't investigated why the server
doesn't handle the signal gracefully.

A workaround is to arrange for the server to start with either
-terminate or -noreset flag to avoid the race.  E.g.

    $ startx -- -terminate
