What is it you're trying to do? Deliberately causing your requests to block each other doesn't sound very scalable. Also, sleeping for only 1 millisecond will likely eat a ton of CPU while it spins waiting for the lock.
It's hard to comment without knowing what you're trying to do. Maybe if you can explain a little more about what it is, people in this group will be able to suggest a better way.
