Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Software Transactional Memory (1997)
I think you are right about STM being roughly equivalent to snapshot isolation.
What STM offers is an easy way to invent "containers for snapshotted values" aka TVars. Using them carefully may result in better scaling: https://hackage.haskell.org/package/stm-containers

How to achieve "Run at most one parallel async action per user"?
how about use stm-containers?
