I've demonstrated that the behavior is the same with snapshots from
1/1/02 and from 9/1/01.  Therefore, I think it is clear that it is at
least not a recently introduced bug in PLplot.  Whether or not it is a
bug in PLplot at all, is yet to be determined, it may still be in my
code.  However, I haven't been able to find the cause yet.  Somehow it
seems that when running the tk driver, somehow my code cores and the
message is coming from plserver, saying the host app is dead.  When I
run the host code in the debugger, it sometimes claims to have ended
with a SIGPIPE.  Doesn't make any sense to me.  yet.  Using any other
device seems to work fine.
