It has become a point of pride that KDE went through all its code to get ri=
d
of memory leaks found by valgrind so I suspect that developers for XFree86
and some of the other Linux system libraries will soon follow.  It would be
a nice point of pride with us as well.

In a prior post to this list I documented every PLplot leak found by
valgrind.  See
http://sourceforge.net/mailarchive/message.php?msg_id=3D1785861.  To fix th=
ese
should be straightforward so I strongly encourage somebody with a good
understanding of plplot initialization and termination to take up this
challenge.

Once PLplot has a clean bill of health from valgrind, it will be most
interesting to see whether the windows debugger still finds memory leaks
(and whether they are associated with PLplot or the windows libraries that
it uses).
