Bug #17791: Ractor exception when using Nokogiri
https://bugs.ruby-lang.org/issues/17791

* Author: tomanderson (Thomas Ender)
* Status: Open
* Priority: Normal
* Backport: 2.6: UNKNOWN, 2.7: UNKNOWN, 3.0: UNKNOWN
----------------------------------------
Parsing xml using nokogiri:
``` r
  doc = Nokogiri.XML('<foo><bar /></foo>', nil, 'EUC-JP')
```
Suppose I want to parse 4 xmls with 4 ractors, it will raise an unsafe exception:

Ractor::UnsafeError: ractor unsafe method called from not main ractor

the ruby version is 3.0.1.

I wonder if there is any way to avoid this.
