Test of ActiveRecord connections in a multithreaded case

On my computer, running jruby-1.7.2

Happy case:

mtarcon $ env wait=1 close=1 threads=300 bundle exec ruby run.rb

Testing with 300 threads using `connection.close`. 1 connections in the pool, 1 second wait time.

Elapsed real time: 2.026 seconds

Failing case

mtarcon $ env wait=1 close=0 threads=5 bundle exec ruby run.rb

Testing with 5 threads not using `connection.close`. 1 connections in the pool, 1 second wait time.
