Gregory's ServerCustomer asked me to create a table for uniqueness checking:
```sql
CREATE TABLE created_uuids (
id UUID NOT NULL PRIMARY KEY
);
```
Pull your own conclusions.

 @ocramius hey now at least that 1 in 4 billion chance of collision at a specific second will no longer be possible! πͺπ€  @ocramius how many UUIDs are they planning on generating at a time that they're legitimately concerned about collisions?  Did the customer also request, for each UUID you generate, you check it is not already listed in there? |
@ocramius Pretty unique request!
