I'm seeing libc.so.6: 
% ldd ./auto/Time/HiRes/HiRes.so
    librt.so.1 => /lib64/librt.so.1 (0x00002af3572c2000)

What do you get when you run this script? 
use Time::HiRes;

open(SMAPS, "/proc/$$/smaps");
while (<SMAPS>) {
  if (m/^\d/) {
    chomp($lib = (split(' ', $_))[5]);
  } elsif (m/^Size:\s*(\d+.*)/) {
    my $size = $1;
    print "$size $lib\n" if ($lib =~ m/HiRes/);
  }
}

I am getting (Centos 5.5, perl 5.8): 
24 kB /usr/lib64/perl5/5.8.8/x86_64-linux-thread-multi/auto/Time/HiRes
+/HiRes.so
2044 kB /usr/lib64/perl5/5.8.8/x86_64-linux-thread-multi/auto/Time/HiR
+es/HiRes.so
4 kB /usr/lib64/perl5/5.8.8/x86_64-linux-thread-multi/auto/Time/HiRes/
+HiRes.so

Does the 2044 kB entry represent real memory usage (unshared with any other library)? I'm trying to determine how much real memory my application is using.
