Description
Executing excon test suite with Ruby 3.1 and OpenSSL 3.0, I observe following errors:
Excon basics (ssl) ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
[2022-02-23 03:58:50] ERROR OpenSSL::SSL::SSLError: SSL_read: unexpected eof while reading
/usr/share/ruby/openssl/buffering.rb:80:in `sysread'

/usr/share/ruby/openssl/buffering.rb:332:in `eof?'

This reminds me issues I had with Puma. There is also more details in ruby/openssl ticket

Research direction
Start by reproducing the failure with Ruby 3.1 and OpenSSL 3.0 while running the Excon test suite. Read the reported paths in openssl/buffering.rb and webrick/httpserver.rb and server.rb, then compare the behavior with the linked Puma and ruby/openssl discussions. Done would require an agreed compatibility fix or a documented reason the error is expected.
