Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

I was editing a fairly normal, fairly small perl script (about 150 lines, 
about 200 bytes) when response got very slow (it eventually came back to 
life;  it should not take seconds to insert a single character, even if 
the character may trigger some action, such as code indentation.  One 
would think that the code indenter keeps some state information).

I've tried turning off the whitespace 'feature', which does seem to make 
some difference, but emacs will still hang on occasion.


I have been having much worse problems, especially in fortran and f90 
modes, both of which will completely hang.  The minibuffer window also 
tends to have weird garbage in it.

In what mode did that happen? was that perl-mode or Cperl-mode?

Does it help to turn off font-lock?  (Hint: try doing that in a
session started with "emacs -q --no-site-file".)
