What I did
Adjust the flow of logic around making a new transaction to reduce the likelihood of a threadlock. Also improves the verbosity with a tx to show when things are still working (particularly when the tx was broadcast but has not yet shown in the mempool).
How I did it
The main thing happening here is removing the use of web3.py's
wait_for_transaction_receipt
and applying similar logic directly in brownie. This gives us some more control over how everything is handled and allows the improved verbosity.For the locks, I reduced the amount of logic inside the lock to only broadcasting the actual transaction.
