Preemption in userspace lock-free programming can be leveraged as a sunk cost, using interrupt-driven memory ordering (e.g., x86's IRET barriers) to ensure visibility of writes without explicit barriers. This approach enables efficient event counts and hazard pointers by relying on interrupt timing to detect global write visibility, reducing overhead compared to traditional synchronization.
