Hi Jim,

Like you I've used shell mode for years. The problems you see started
a few years ago, showing up in the OS X build; now they are in the
Linux build as well.

This week I'm in Japan and am meeting with one of the maintainers. I
am hoping to demo these bugs to him and get his feedback. It's high
time these were addressed.
