Issue Description

When trying to upgrade our sentry-ruby version from 5.21 to the latest 5.22, I noticed the following error:

ThreadError resque:no_fork resque:work
Unhandled
can't be called from trap context (ThreadError)

The trace indicates the error is coming from sentry-ruby/lib/sentry-ruby.rb at line 310 from inside get_main_hub.
get_main_hub was indeed updated in the last release, but I can not say why is generating the error above.

Reproduction Steps

I don't know what triggers it.

  )
  config.generate_fingerprint = false
end

@solnic this is because of the new mutex, not sure why it happens.
