ds@1952:  * Notes:
ds@1952:  *
ds@1952:  * 1) All queries in here are high priority.  This is because the admin stuff 
ds@1952:  *    is very important.  Do not take this to mean that in your script, 
ds@1952:  *    everything should be high priority.  
ds@1952:  *
ds@1952:  * 2) All callbacks are locked with "sequence numbers."  This is to make sure 
ds@1952:  *    that multiple calls to sm_reloadadmins and the like do not make us 
ds@1952:  *    store the results from two or more callbacks accidentally.  Instead, we 
ds@1952:  *    check the sequence number in each callback with the current "allowed" 
ds@1952:  *    sequence number, and if it doesn't match, the callback is cancelled.
ds@1952:  *
ds@1952:  * 3) Sequence numbers for groups and overrides are not cleared unless there 
ds@1952:  *    was a 100% success in the fetch.  This is so we can potentially implement 
ds@1952:  *    connection retries in the future.
ds@1952:  *
ds@1952:  * 4) Sequence numbers for the user cache are ignored except for being 
ds@1952:  *    non-zero, which means players in-game should be re-checked for admin 
ds@1952:  *    powers.
