FIFO

TRFifo provides strictly ordered FIFO (First In, First Out) serialization of task execution. Tasks are guaranteed to run in exactly the order they registered with the resource.

Characteristics:

• Linked list implementation scales efficiently to many waiters
• Strict FIFO ordering guaranteed
• Only one task runs at a time (serialized)
• No possibility for tasks to "cut in line"

When to use:

• Need guaranteed execution order
• Large number of waiting tasks
• Processing queue-like workloads
• Serializing access to order-dependent resources

Example use case: Serializing writes to a file or database where order matters.
