Unfortunately my computer becomes quite unusable after that. X process 
jumps to 100% CPU usage, XEmacs process jumps to 40% (it's a SMP system).

Yes.

`interprogram-cut-function' is a variable declared in Lisp.

Value: own-clipboard

`interprogram-paste-function' is a variable declared in Lisp.

Value: get-clipboard-foreign

`x-selection-strict-motif-ownership' is a built-in boolean variable.

Value: t

The values are the same for "xemacs -vanilla". Setting the last variable 
to "nil" doesn't fix the problem.

BTW: The problem is the same with Ctrl-W (kill-region).
