I regularly (a few times every week or so) have an emacs that is not
responding. It seems to happen in a function (outside emacs) named
XIfEvent, i.e. if I do "fin" in gdb, it'll work until I get to XIfEvent.
It happens on my laptop but I don't think I had the problem on my
desktop even though I use a similar setup there. Here's a full bt :
