1.326. On the DescriptorImpl, .clogged == true yet .runners == []. From a script
console, .queue.entries.keySet() shows several runners. .inProgress contains
QueueEntry's, not Runner's. I think the bug is in
SequentialExecutionQueue.getInProgress.

Workaround:

for (runner in
hudson.model.Descriptor.find('hudson.triggers.SCMTrigger$DescriptorImpl').queue.entries.keySet())
{
println(runner.target.displayName + " " + runner.duration)
}
