I've been trying out the GC::Profiler and noticed an oddity in the report generated on Ruby 2.2.0
via GC::Profiler.report. The report generated outputs a really large value under Use Size header
on 2.2.0 but this is not present in 2.1.0. This particular large value remains the same (as far I've
tested it in multiple runs) across different runs.

I've posted the sample code and the report results for both Ruby 2.1.0 and Ruby 2.2.0
at this link: https://.com/kgrz/gc_profiles

Notice the Use Size column's output in Ruby 2.2.0 in two runs:

Run 1: https://.com/kgrz/gc_profiles/blob/master/2.2.0-read.txt
Run 2: https://.com/kgrz/gc_profiles/blob/master/2.2.0-read-run-two.txt
