06:50 AM Ruby Feature #20805 (Feedback): Allow Ractor#send from a signal trap Proc

It was surfaced in https://bugs.ruby-lang.org/issues/18139 that Ractor is designed to "unexpected interruption free" and it's not supposed to have a `kill`-like method.
A better alternative to that would be allow the main Ractor to co... kirs (Kir Shatrov)

08:06 PM Ruby Bug #18193 (Closed): Accessing global configuration from Ractors

Consider a very common Ruby code with `attr_accessor` on a class:
``` ruby
class GlobalConfig
class << self
attr_accessor :option
end
end
GlobalConfig.option = 123
GlobalConfig.freeze
puts GlobalConfig.frozen? # =>... kirs (Kir Shatrov)

09:27 PM Ruby Bug #17420: Unsafe mutation of $" when doing non-RubyGems require in Ractor

(coming to this bug from https://bugs.ruby-lang.org/issues/17477)
I think it's fine to force `require` to be called only from the main thread/ractor, at least for now. I can imagine that would simplify a lot of things.
I'd like to ... kirs (Kir Shatrov)

09:23 PM Ruby Bug #17489 (Closed): Ractor segfaults

I was able to boil it down to this script:
```ruby
require 'bundler/inline'
gemfile do
source 'https://rubygems.org'
gem "sinatra", "~> 2.1"
end
require 'sinatra'
class App < Sinatra::Base

08:44 AM Ruby Feature #17145: Ractor-aware `Object#deep_freeze`

I'd really like to support this change for reasons I've describe in https://bugs.ruby-lang.org/issues/17180
We can take something as simple as `URI::parse("http://example.com")` as an example. Right now that can't be used from a Ractor ... kirs (Kir Shatrov)

09:33 PM Ruby Misc #17180: Ractor and constant referencing

Another example:

parser = Ractor.new { CREATOR }
Ractor.select(parser)
```
```
