One could hope for a more cooperative response, I think.  It took me
all of 5 minutes, without knowing anything about icicles and very
little about the new implementation of universal-argument, to convert
your test file to the current sources (see the attached).  With it, I
convinced myself that the bug is indeed fixed: typing the first 's'
interrupts the wait immediately, and displays "ssss" in the echo area.

Please verify that my changes to the test file are valid and the bug
is indeed fixed.

Thanks.
