[Rd] segfault (with non-standard use of x11/par(ask=T))

[Deepayan Sarkar]

On r-devel, I'm getting a segmentation fault from an admittedly strange 
sequence of events:

(on a fresh session)

> x11()
> x11()
> par(ask = T)
> plot(1)
Hit <Return> to see next plot:

<at this point, instead of hitting Return, kill 
the second X11 window (using the mouse, for example), 
THEN hit Return.>

Segmentation fault

This doesn't happen in R 2.0.1, but has been there in r-devel for a 
while now.
