Only as a side note: I have some version of MP (it claims to be
1.002), but hard to tell which one exactly, and it doesn't hang.

I don't have gv (so I don't see the bug that you mention), but thanks
for the example. Skim (on Mac OS X) also seems to have a really weird
bug: at some scaling (not always) the round corner of the pen simply
disappears.
