Please submit a bug report (with "M-x report-emacs-bug RET"), and
please show a recipe starting with "emacs -Q" for reproducing this
progressive slowdown.  If you need to visit specific files for
reproducing the problem, please try using files that are part of the
Emacs source tree, or else tell where to get those files.

Thanks in advance.

Bugs should be fixed, not worked around. ;-)
