After a (long) while, it does seem to terminate the clipboard protocol
and things are back to normal performance.

It could seem like the clipboard program (KDE klipper) is slow,
but it does seem to get the whole data eventually.

FWIW, klipper on KDE 3.3 does not seem to have this problem, it completes almost instantly. The timeout in Emacs is 20 seconds per part, each request is close to 256 kbytes (depends on your X server, but max request for X is typically 64k words (word == 4 byte). You can get the exact value from the defun x-server-max-request-size (note: this is the number of 4 byte words). So with this you can calculate how long the max time is.

You can also shorten the time out time, it is in the variable x-selection-timeout and see if it helps. If it does, it means that the timeout handling or the property change detection code in Emacs has a bug, if indeed klipper gets the whole data eventually.
