I'm pretty sure that any scheme that tries to use module reference
counting will either be horribly complex, still have subtle races, or
(mostly likely) both.

The sanest solution at least for the SA query module would be to make
every consumer get some sort of client cookie, and then have the
function that destroys the cookie wait for all callbacks to finish.
