Support for rails 6

[stepozer]

I successfully use your gem for our legacy project in previous year. It speed up my specs loading. Thank you! But right now we updated ruby on rails from 5 to 6 version and Zeus crashed. I also tested with new rails 6 application, and it also did not working.

Do you have any chance watch the problem?

Thank you again.

It'd be great to have a dummy app with an example.
At least you may have a problem with bootsnap - #617 (comment)
Please, let us know if it fixes your problem.

@maslenkov My boot.rb does not contain bootsnap:

# Set up gems listed in the Gemfile.
ENV['BUNDLE_GEMFILE'] ||= File.expand_path('../../Gemfile', __FILE__)

require 'bundler/setup' if File.exist?(ENV['BUNDLE_GEMFILE'])

When I try start zeus I see this error:

What is the output of commands like zeus server?
As you can see on your own screenshot - zeus server (alias: s) [run to see backtrace] - zeus suggests running zeus server to see backtrace.
(BTW: it'd be nice to compare output right after zeus start and on the second run, some times it can be different).
