I am looking at the copy/paste mechanism and I noticed that for some reason, on X11 (i.e. GNU/Linux), there is different code for getting the info to paste. There is this comment:
/* in X windows the selection already went to the clipboard when it was made; here we "copy" it to our own buffer as well, because, annoyingly, the clipboard will usually be destroyed by the time the user asks to "paste". */
On Win32 and Mac OS X, pd gets the text from Tcl/Tk using [clipboard get]. It would make things cleaner if everything used the same code. Is there any reason not to make X11 get the data from Tk, if possible?

Well, it didn't work for me when I tried it - if you select text in one object, hit "copy", then select text in another intending to paste over it -- bingo, X does a new "copy". ouch.

Most likely Miller is confused because in X11 there are two paste mechanisms, which one could call select+paste and copy+paste. I just used [clipboard get] with Ctrl+C and Ctrl+V on Linux and I don't recall anything wrong with it.
The select+paste system instead uses Button-2 (middle-click or thumb-click or wheel-click depending on which mouse) to paste directly from the selection instead of from the clipboard, because then there's no real clipboard in that system.
Right?

Yep, I'm clearly getting fooled by select-paste, if that's indeed what it's called. But at least when I tried it, pasting from the "clipboard" appeared to paste instead from the selection. Or maybe I was doing it wrong...?

I think here's the explanation: "X distinguishes the PRIMARY selection (typically <ButtonPress-2>) from the CLIPBOARD selection (used for explicit "Cut", "Copy", and "Paste")."
