In memory queue v2

[amber mulch]

How would you implement an in memory queue? In general I want an endpoint to create a job, which will be executed. However, no more than one job should be running at once. Note that by in memory queue I do not mean redis. I don't want to depend on any other services. I also don't care about jobs that are lost.
