For something like this, I don't think it's a big deal.

A bigger deal is that it now wants perl-bigint, as of commit
8d8a77fb99bd ("leaking_addresses: add range check for vsyscall
memory").

And that is not apparently a common enough perl module to be installed
by default.

Sure, I just ran

    dnf install 'perl(bigint)'

and it did the right thing, but it does seem to be something of an
inconvenience.

And things are *slow*, to the point of breakage. I get

  timed out parsing: /proc/kallsyms
  timed out parsing: /proc/2177/smaps
  timed out parsing: /proc/2238/smaps
  timed out parsing: /proc/2336/smaps
  ...

and no actual output. I'm not sure what's up with that, and whether
it's related. Probably not, but I didn't start bisecting.

So I pulled it but then unpulled it due to issues during testing.
