I don't know whether I've been affected by the problem or not, and I 
don't think many who don't do their own perling would. A lot of the 
things I run are set to run when I'm not present, and if I'd upgraded my 
  C4 systems to C5 I might not notice if some jobs went from taking a 
few minutes to an hour and more, depending of course, on how many: 
assuredly, if the system went to loadaverage >20 I would. And, I have a 
C5 box that does do this, and I don't know why. It is, however, a fresh 
install and not an upgrade.

And I don't particularly think that Perl is the problem, though it could be.
