I've just updated a tmp DomU machine :
Without the updated perl :
time /tmp/perlbug.pl
..................................................
real    0m21.473s
user    0m21.345s
sys     0m0.044s

with perl.x86_64 4:5.8.8-10.el5_2.3.centos from Testing :
time /tmp/perlbug.pl
..................................................
real    0m0.214s
user    0m0.188s
sys     0m0.024s

The test was run several times with approximatively the same results 
(and after a reboot too)
The perl script used was the one someone posted on the CentOS list 
recently :

------------- bug test ----------
#!/usr/bin/perl
use overload q(<) => sub {};
my %h;
for (my $i=0; $i<50000; $i++) {
$h{$i} = bless [ ] => 'main';
print STDERR '.' if $i % 1000 == 0;
}
----------------- end snip ------------

I'll test on other machines but i admit i'm not a Perl user myself nor 
have perl scripts that i use for day-to-day operations
