The more recent comments on this issue are actually unrelated.

If a paste is large enough to fill the shell's line-buffer,
then that will "delay" a ^C.  I've seen a few comments about that,
and it's not due to xterm.  xterm isn't going to detect ^C in
the input and magically honor that in some undocumented out-of-band
signalling mechanism.

The reported issue did not depend on that, so unless someone can
provide detailed instructions on how to bump into a 4000-character
limit on current systems, this can be closed.
