Description of problem:

Using the same connection from two threads causes a segmentation fault.

Version-Release number of selected component (if applicable):

4.1.8

How reproducible:

Always.

Steps to Reproduce:

Run the following program:

---8<---
#!/usr/bin/ruby
  
require 'ovirtsdk4'

# Create the connection to the server:
connection = OvirtSDK4::Connection.new(
  url: 'https://jenkins-vm-22.qa.lab.tlv.redhat.com/ovirt-engine/api',
  username: 'admin@internal',
  password: '123456'$q qp
  insecure: true,
  debug: true
)

events_service = connection.system_service.events_service

a = Thread.new do
  loop do
    events_service.list(max: 10)
  end
end

b = Thread.new do
  loop do
    events_service.list(max: 10)
  end
end

a.join
b.join

connection.close
--->8---

Actual results:

The program crashes with a segmentation fault.

Expected results:

The program should run without problems.

Additional info:

This happens because the way we use the underlying library, libcurl, doesn't support access by multiple threads.
