ex_banking's Issues

Handle sender withdraw request more gracefully when receiver reached max requests limit

We need to make sure withdraw and deposit should be concurrent. When both users's involve in send transaction, there's a chance when send withdraw happens, receiver already reached max requests limit.

Now the question is how? We can wait for both sender and receiver to have requests < 10 in any given moment of time. Once both sender and receiver have enough requests, we can execute logic to to withdraw and deposit at the same time.
