Hand-over-hand Locking.

I am trying to decide on my record locking technique and the "hand-over-hand locking" method presented in Monkhouse's book seems to fully fulfill word for word my following assignment requirement:

"If the specified record is already locked, the current thread gives up the CPU and consumes no CPU cycles until the record is unlocked."

Do any of you know whether there would be another way to fulfill this requirement? I am just a bit worried that this technique might be considered too complex for a junior developer to understand. Anyone out there used this famous "hand-over-hand" locking method and obtained the magical 80/80 score?

Thanks for all replies.

I agree. Here's the link:
