That's described in the initial report. I see it's called "term-mode"
not "terminal-mode" which was a brain-fart on my part. The steps
(term-mode in step 2):
1. Start "emacs -nw" <ret>
2. M-x term <ret> <ret>
3. In another application (for the purposes of "exact keystroke, let's
say, Alt-TAB to Firefox"), copy some text into the clipboard, it
doesn't matter what.
4. Return to the Emacs session (click on the Terminal emulator,
Alt-TAB, whatever*), and paste into the terminal (I used Command-V).
4* To be clear, return the cursor to the term-mode buffer (e.g., C-b
*terminal* <ret>).
Inject any mount of delays or operations between steps 1, 2, 3, and 4.
The bug essentially is "if you ever paste into term-mode buffers, you
lose.
