RLock to multi-thread synchronization

sponsored links
Problem scenario:
There are multiple threads, are responsible for the construction of houses, trees, gardening and the like work, which requires a certain waiting time, waiting for the process need to communicate with the server to stay connected. Submission can not be too frequent connection, preferably 2-3 seconds again.
For this synchronization between multiple threads can use RLock to achieve lock mechanism.
