Hey,

It might not be solvable, but at least I think it = is worth discussing and documenting. Who knows if this could not end in a D= ONT-DO sort of document, which might also be of some merit and use.

Happy easter, /PA

I seem to be unable to reproduce this.

Does the freeze happen only if you resize the frame?=C2=A0 What if you just=
drag the mode line to resize the window?

And when you say "freezes", does it mean Emacs uses 100% of a CPU= 's
execution unit, or does it mean it waits for something doing nothing?

Btw, in general, having arbitrary expressions in mode-line's :eval
form might definitely cause problems, since the mode line is called by
redisplay.
