Details:

If I call pause() several times in a row, with only a little work done in
between calls, eventually pause() starts taking much longer than the specified
time, causing hangs.

```
octave:1> for i = 1:100; t0 = tic; pause(0.2); te = toc(t0); fprintf("%.3f\n",
te); endfor

Only seems to affect CLI Octave; doesn't happen in the GUI Octave.

Affects 4.4.1, 5.1.0, and default.
