Bug #20803: Windows intermittent spec failure - ObjectSpace.memsize_of(:abc)
https://bugs.ruby-lang.org/issues/20803#change-110219

* Author: MSP-Greg (Greg L)
* Status: Open
* ruby -v: master
* Backport: 3.1: UNKNOWN, 3.2: UNKNOWN, 3.3: UNKNOWN
----------------------------------------
This frequently fails on ruby-loco's mingw build, but I think there have been less frequent failures on ucrt and mswin.  I've started a new GHA build when it occurs, and it usually passes.  I could not repro locally.

```
ObjectSpace.memsize_of returns 0 for literal Symbols FAILED
Expected 40 == 0
to be truthy but was false
/ruby/spec/ruby/library/objectspace/memsize_of_spec.rb:16:in 'block (2 levels) in <top (required)>'
/ruby/spec/ruby/library/objectspace/memsize_of_spec.rb:4:in '<top (required)>'
```

The test code:
```ruby
it "returns 0 for literal Symbols" do
  ObjectSpace.memsize_of(:abc).should == 0
end
```
```
