Suspected native thread leakage in Slick 3.0.0-M3

[adatoo]

Environment:

• Play Framework 2.3.8
• Postgres JDBC Driver 9.4-1201-jdbc41
• JDK 7 / 8

Having followed (this)[http://blog.knoldus.com/2015/03/03/play-with-reactive-slick-a-simple-crud-application-in-play-framework-using-slick-3-0/] article to integrate Slick into Play, I am finding that running my full test suite results in a java.util.concurrent.ExecutionException: java.lang.OutOfMemoryError: unable to create new native thread error. Testing a subset of the tests works fine.

Stacktrace:
