Just this morning,
I found (again!, we had something close to this before)
the following related bugous behavior :
After interrupting a plot (which would have taken a few minutes and was
"wrong" anyway), starting another plot, interrupting again [with C-c],
and maybe the same once more,
R started just giving a ">" prompt
but did not react any further at all.
(C-c would return the prompt, but no other reaction was possible)
Only killing the R process helped.
I may try to reproduce more exactly later today.
