Still weird: this says that Emacs simply waits for any input to
arrive, a.k.a. "is idle".
You've mentioned before that one of the two scenarios where you see
this problem produces a much longer delay -- could you repeat the same
procedure during that long delay, and show the backtrace from that
session? Maybe we will see something more interesting there.
Thanks.
