Bug #19154: Specify require and autoload guarantees in ractors
https://bugs.ruby-lang.org/issues/19154
* Author: fxn (Xavier Noria)
* Status: Open
* Priority: Normal
* ruby -v: ruby 3.2.0preview3 (2022-11-27) [x86_64-darwin22]

Given a file `c.rb`:
```ruby
class C
end
```
the following script:
```ruby
r1 = Ractor.new do
require './c.rb'
end
r2 = Ractor.new do
require './c.rb'
end
r1.take
r2.take
```
raises:
```
% ruby -v foo.rb
ruby 3.2.0preview3 (2022-11-27) [x86_64-darwin22]
foo.rb:1: warning: Ractor is experimental, and the behavior may change in future versions of Ruby! Also there are many implementation issues.

```
Would it be possible to have documentation about their interaction?
This is important also to understand autoloading within ractors, since constant references may trigger `require` calls.
