Bobus,

When I was solving a similar problem, I did try out the approaches
suggested by Hugo and Erland. I hate to say that, but I was always
getting a bottleneck because of lock contention on PinsTable. Maybe I
was missing something at that time. I had a requirement to produce
hundreds of PINs per minute at peak times, so I decided to allocate a
batch of PINs at a time, instead of distrributing them one at a time -
that took care of lock contention
