12:22 AM Ruby Revision 2c2eaa31 (git): [ruby/rubygems] Fix constants in TAR to be frozen

I would like to use the tar implementation inside a Ractor, but two of

I personally agree with this. If I write an infinite loop, I expect it to loop infinitely, even if I wrote the infinite loop by mistake. Calling... tenderlovemaking (Aaron Patterson)
