Thanks John,
As the problem can be reproduced, I would like to submit this as a bug
report. But I think someone will have to add me to Bugzilla first.
Given the few responses, I am not expecting that this will get a high
priority though...

Dear Martin and Jon,
I can reproduce this problem in the Windows GUI, where I observed it using
Jon's program after 75 iterations. I didn't observe the problem in a Windows
terminal or under RStudio, letting the program run for more than 200 iterations
in each case.

Please Windows users .. this is possibly only for you!
Note that I do *not* see problems on Linux (in ESS; did not try RStudio).
Please also indicate in which form you are running R.
Here it does depend if this is inside RStudio, ESS, the "Windows GUI", the
"Windows terminal", ...

"some versions of R" ... all on Windows ?
