bundle installs hangs with ruby 3.4.7

[Daniel Abrahamsson]

Hi,

I have a problem with `bundle install` hanging with ruby 3.4.7. 
Downgrading to 3.2.2 solves the problem.

Here is my Gemfile:

----
source 'https://rubygems.org'

gem 'asciidoctor', '2.0.23'
gem 'asciidoctor-bibtex', '0.9.0'
gem 'asciimath', '2.0.5'
gem 'coderay', '1.1.3'
gem 'rouge', '4.3.0'
gem 'asciidoctor-diagram', '2.3.1'
gem 'pygments.rb', '0.6.3'
gem 'text-hyphen', '1.5.0'
gem 'asciidoctor-pdf', '2.3.17'

----

Here are the commands I run:

$ bundle config set --local path '_ruby-deps'
$ bundle install --verbose

If I try to cancel the installation with Ctrl+C, it shows a backtrace, 
but continues to run. If I press Ctrl+C again it shows the backtrace 
again. After that, it just hangs and I have to force kill the ruby 
process). Here is the backtrace:

A workaround is to limit the number the number of workers to 1, like this:

$ bundle config set --local jobs 1

I'll go with that workaround for now, but I want to bring attention 
about this issue to the maintainer.
