Emacs didn't use to lose > characters in that scenario. I have a hard time believing this. Unless the OS itself drops the characters (and I don't think any modern OS does), you'd have to come with a plausible hypothesis for how this can happen on a particular OS with a particular mechanism of keyboard input handling by Emacs on that OS. Doesn't the OS buffer keys without discarding them until the application actually reads them? On systems that use interrupts for Emacs keyboard input, what happens with the keys you type if the interrupts are blocked for prolonged times? I hope Emacs never ignores these interrupts, but what happens if it does? Once a key was read by Emacs, there's simply no mechanism in Emacs I know of to "drop" it.
