Well, that's the question, I suppose. I'm thinking that I may have 
misunderstood the issue. The production server running 2.3.14 is a 32-bit 
RHEL 3 system. The VM I'm using for 2.4 is a 64-bit RHEL 5 system. Its Perl 
binary uses 32-bit ints. I thought previously that I would have to rehash 
the 2.3 spool for that to work, but now I start to think that I don't, 
because the hashing algorithm hasn't actually changed, and the Perl part 
has been fixed. The only problem would have been trying to use the broken 
Perl code in 2.4.14. Is that correct?

Thanks, Sebastian
