This patch should work around that problem by using the system

Seriously: I started to implement this as a fix for 2138 over a
year ago, but never found the time to finish it, because at that
time it was far more complicated. When I realized that it could
fix this problem as well (at a possible performance cost, we need
to investigate that) I could not resist to try to finish it.
Thanks to some cleanup that has happened during the last months it
was now quite easy to get it working. This patch is not well
tested and has a lot of debug output (+ some error handling
missing), but if this is OK to go in I plan to polish it when I
find time.
Quite frankly I am not very confident that you can achieve the same
performance as the internal Clipboard. You are putting in the chain
lyx2lyx parsing + lyx format parsing which is known to take some
time. Right now, I can copy and paste the full UserGuide.lyx into
another document without _any_ delay. I doubt this would ever be
possible with your solution.
Moreover, we have now the multiple view feature so we don't need
this feature anymore.
If we are going that route then I would prefer that you use binary
dump of the internal structure instead.
Sorry for not being optimistic about this. Moreover I really think
that the Clipboard/Selection stuff is OK right now for 1.5, the Mac
problem can be cured without this hammer solution IMHO.
Well, it does work on Mac: insets and formatting are correctly cut-
and-pasted within LyX (though cutting and pasting between LyX and
other programs destroys the formatting and deletes the contents of
insets, which I assume is intended behavior).
As for speed, I can cut a 110,000 word document in about 2 seconds
and paste it in about 1 second with this patch. (Without the patch
it's very quick -- < .25 second -- but, of course, without formatting
or insets.)
