Multiple concurrent executions of the same pipeline?

Hi folks,

I’m wondering if I’m misunderstanding the buddy behavior when it comes to concurrent execution of multiple pipeline instances – ie: 2 PR executions on the same pipeline at the same time.

Is this not supported? I see the following in the build logs, which imply it’s either unsupported or I’ve not configured it correctly:

Processing of buddy.yml started...
Processing pipeline <my pipeline name here>
Processing pipeline <my pipeline name here> skipped. Pipeline is being executed or is enqueued.
Processing of buddy.yml finished.

Can somebody advise if we can have 2 branch executions concurrently building in the same pipeline?
