Spans from the same transaction share the dropped spans map. If they end concurrency a race condition could happen when updating the map. Add a RW lock to prevent that.

I've added a test and discovered more issues. It seems this is affecting more than just the dropped spans. I've pushed some changes and added a test. |

Where should I add that ? Looking at past releases, we're adding all the changelog entries on release |
|
@simitt could you clarify the above question ? |
|
@kruskall in the past we have added entries to the Unreleased section. We've not been consistent about it though, and have sometimes just added the entries retrospectively at release time. Let's merge this and create a patch release - either adding the entry now, or creating the section at release time. |

Apologies @kruskall , I missed your message. |

This reverts commit 7fe3968.
The previous fix didn't cover all cases. The issue is deeper and affects more than the transaction data. We need to always acquire the tx lock before ending the span.
