So it will still be a application window?

Groan, yes. As I recollect, halfwin's are a hack to marry a window with a
pseudo-tty. I never worked on this part, aside from making it compile
during the initial port. A better bet would be to look at the pop-up
windows which icon/zoom.c uses.

I wrestled with some thorny edge cases in the multiple window handling, and
got it working acceptably about a year ago. Bit rot could certainly have
won back this fix, or perhaps a new variation has come up.

The real pain with debugging this level of MGR is that your screen and
keyboard are held by MGR, so there's not a good place to run the debugger.
Back when I was hacking on this, I was on the road with my 2-pound laptop,
and was actually running adb on the terminal emulator of my Psion 3
connected to the COM1 port!
