What is an RLock and how is it different from a regular Lock?
Think about accessing shared resources more than once.
Can RLocks help prevent deadlocks?
Consider how functions can call themselves.
What does RLock stand for?
Focus on the meaning of 'Reentrant'.
Can a thread deadlock itself when using RLocks?
Think of how RLocks are designed to function.
Design a class that simulates a bank account with methods to deposit and withdraw funds. Ensure that both methods can be safely called by the same thread in quick succession without deadlocks.
You will need to implement methods that acquire and release the RLock.
In a factory simulation, two types of machines are dependent on each other to complete tasks. Create a threading scenario where using RLocks prevents deadlock while allowing different threads to complete their tasks.
Think about tasks that might call each other in a loop.
