+  withTaskQueue creates a queue of "tasks" (just plain closures to execute), and executes them with your desired level of concurrency.
+  This way, you can define, for example, 40 things that need to execute, then only allow 10 of them to execute at once.
+
+  Each "process" will execute in a separate, unique, empty directory.
+  If you want each process to have a bootstrapped kibana repo, check out kibanaPipeline.withCiTaskQueue
+
+  Using the queue currently requires an agent/worker.
+
+  Usage:
+
+  withTaskQueue(parallel: 10) {
+    task { print "This is a task" }
+
+    // This is the same as calling task() multiple times
+    tasks([ { print "Another task" }, { print "And another task" } ])
+
+    // Tasks can queue up subsequent tasks
+    task {
+      buildThing()
+      task { print "I depend on buildThing()" }
+    }
+  }
+
+  You can also define a setup task that each process should execute one time before executing tasks:
+  withTaskQueue(parallel: 10, setup: { sh "my-setup-scrupt.sh" }) {
+    ...
+  }
