[SR-Users] limiting concurrent calls with dialog module

[Alex Balashov]

Graham,

Good deal.  The one improvement I would suggest would be to use sqlops for custom DB queries as it is more flexible, and is the canonical way to do them now as of >= 1.5.0.  avp_db_query() could go away at some point.
