Thank you for the code, but this is not the problem I'm trying to solve. We
allocate UIDs centrally. It's more a policy question:

Is the range 500 <= n < 1000 likely to be free in the future?

What about using the range 30000 < n < 65535?

We allocate UIDs now and want to avoid future UID conflicts. Changing UIDs on
large-scale infrastructures is painful.

Regards

Christian
