1.8.0 on Unix: interrupting huge print()s ??

NEWS for R 1.8.0 has

 USER-VISIBLE CHANGES

     <......>

     o	On Unix-like systems interrupt signals now set a flag that is
	 checked periodically rather than calling longjmp from the
	 signal handler.	 This is analogous to the behavior on Windows.
	 This reduces responsiveness to interrupts but prevents bugs
	 caused by interrupting computations in a way that leaves the
	 system in an inconsistent state.  It also reduces the number
	 of system calls, which can speed up computations on some
	 platforms and make R more usable with systems like Mosix.

and this has already caused grief here
(actually it has several days ago, when I switched our users to
 R-1.8.0beta  __ BUT THEY DIDN'T TELL ANY R DEVELOPER __ )

for a user who does use *large* matrices.

When accidentally calling print() {implicitly}, we have been
used here to press CTRL+c (twice in Emacs ESS!) for stopping the
output.

This no longer works in R 1.8.0 at least on our unix platforms.
To reproduce, type

  cbind(1:1e6)

and try to cut it short (it only takes a minute or so,
whereas our user here had a matrix that needed more than 10
minutes of screen output !)
