Yeah, sorry, was busy with other stuff. Probably a good idea for me to take a look at all pr's we have...

This particular lock is actually very important. It helps at least with:
- Concurrent close
- Concurrent keepalive
- Concurrent break
I'm not sure whether changing everywhere to use SemaphoreSlim is a good idea, would have to think about that.

Yeah, still no idea what to do here. @roji maybe you have something on your mind?

It seems like if we're not closing the connector (but, for example, breaking it while opening) the semaphore is not going to get disposed.

We must guarantee that the Dispose/Close method is correctly called once a connector is not usable/used anymore.
Should we check everywhere that this statement is correctly enforced?

@manandre just to confirm, you're waiting on our review for this right? If not, can you please rebase and we'll do our best to review and merge ASAP? Not sure this will happen for 8.0 at this point, but we can always try. |

@roji I have just rebased. However, I am still not fully confident around the lock replacement in the |
