What is the GPars default pool size? <p>I thought this would have been an easy thing to find but I've failed.</p> <p>If I use GPars in my Groovy application and I don't specify a pool size how many threads will be created? Is there a default pool size without setting one?</p> <pre><code>// How many threads will be created? What is the default pool size? GParsExecutorsPool.withPool { // do stuff... } </code></pre>
