How do we improve our locking code, so we don't have to spawn millions of sequences?
What is the locking method you are using?
I am not using locking with the million sequence solution. I do not want something that locks because the problems described below
I prefer the solution generates a gap (skip a couple of numbers) and not using locks.

Now I read this paragraph, I realize I was not clear enough.
I am saying we do not want to use locks because of all the problems described.
