How do I enforce this ordering logic - pipelines.

[Sam Sieber]

Is there a way to make sure that concurrent runs of a pipeline enter a stage in the order they were executed, without aborting any?

I'm putting our unit tests into pipelines. I'd like to wait to calculate the junit report until the previous runs have had their tests calculated.

Example:

A, B, and C are consecutive runs. Normally, A would finish first, then B, then C, but if B for some reason crashes, it might have it's tests recorded before A... and I'd like to avoid that.

My options:

 * Lock - this doesn't work, not if I want the tests to be running concurrently.

 * Milestone - this also doesn't work - I don't want to abort any of the reporting
