How to run SoapUI teststeps in parrallel with Groovy - multithreading

Question

SoapUI has options to run your test-suites and test-cases in parallel but no such thing for doing it with test-steps.
How can I achieve such a thing with a Groovy teststep inside my testcase?
This is my current code:
import com.eviware.soapui.impl.wsdl.testcase.WsdlTestCaseRunner
//Get all Soap type test steps within the testCases
for ( testStep in testRunner.testCase.getTestStepsOfType(com.eviware.soapui.impl.wsdl.teststeps.WsdlTestRequestStep.class)){
//Print out the name for the testStep
tsname = testStep.getName();
log.info tsname;
//thread = new Thread("$tsname")
def th = new Thread("$tsname") {
#Override
public void run(){
//Set the TestRunner to the respective TestCase
TestRunner = new com.eviware.soapui.impl.wsdl.testcase.WsdlTestCaseRunner(testRunner.testCase, null);
//Run them all and then rejoin the threads
log.info("thread: " + tsname)
TestRunner.runTestStepByName(tsname);
def soapResponse = TestRunner.getTestCase().getTestStepByName(tsname).getProperty("Response");
log.info "soapResponse: " + soapResponse;
th.join();
}
}
th.start();
th.join();
}

Managed to fix it myself and posted the answer here for all who stumble into the same problem:
import com.eviware.soapui.impl.wsdl.teststeps.WsdlTestRequestStep
List<String> steps = testRunner.testCase.getTestStepsOfType(com.eviware.soapui.impl.wsdl.teststeps.WsdlTestRequestStep.class)
def map = [:]
//define the threads list, this will hold all threads
def threads = []
def kickEm = steps.each{ step ->
def th = new Thread({
stepName = step.getName();
log.info "Thread in start: " + step.getName();
//Set the TestRunner to the respective TestCase
TestRunner = new com.eviware.soapui.impl.wsdl.testcase.WsdlTestCaseRunner(testRunner.testCase, null);
//Run the corresponding teststep
TestRunner.runTestStepByName(step.getName());
//Get the response of the current step
def soapResponse = context.expand(TestRunner.getTestCase().getTestStepByName(step.getName()).getPropertyValue('Response')) as String;
log.info "In thread "+step.getName()+" soapResponse: " + soapResponse
//Put this into a map, the key is the stepname and the value is its response, so we can retrieve it all outside the each loop
map.put(step.getName(), soapResponse);
})
log.info "Putting new Thread({..}) th back into the threads list";
threads << th;
}
threads.each { it.start(); }
threads.each { it.join(); }
log.info "Map: "
map.each { step, response ->
log.info "Step: ${step} has the response ${response}"
};
log.info "Done!"
