Please try the attached patch. It was indeed clip_gen_set_selection()
that was slow, but the previous patch was still a little bit wrong.
Please also make sure, the clipboard still works. I have tested it
locally and instead of 15 seconds for a :g/^/y command it took 2.5
seconds (as much as with :set clipboard=), while still copying the last
yank into the clipboard.
For the records, I did profiling using ltprof. This worked quite well.
Best,
Christian
