I've noticed that both 21.2.38 and 21.2.39 have a problem when

slow link like an ISDN line between the X Server and a copy of XEmacs
running on Solaris. Some operations (such as copy-primary-selection or
kill-line) transmit a lot more data than they should, around 30K.
truss'ing the X library calls Xemacs makes shows that the time is
spent in the Motif clipboard code (XmClipboardStartCopy,
XmClipboardCopy, XmClipboardEndCopy).
That leads one to select-x.c:hack_motif_clipboard_selection where
there's a comment about this slow behaviour with Motif selections. An
old hack to avoid the problem is commented out because it introduces
correctness problems.
Even with Xemacs running on the same machine as the X server there's a
noticable sluggishness with kill-line. What's the best way to
avoid this? Stop using Motif altogether?
