Not precisely... but it is fun to code :D

Well, one can always store persistent values in a hash table in the C
side of the world, and provide a view of it to the Lua side by adding
e.g. an userdata with table metamethds named "persistend" to every VM
state, so one could handle requests the following way:
if persistent.db_conn ~= nil then
db_conn = persistent.db_conn
db_conn = persistent.db_conn = open_database_connection()
Have a nice day!
Contrary to popular belief, Unix is user friendly.
It just happens to be selective about who it makes friends with.
