Actually it's not doing anything, as I'm just trying to work it all out - just a 

bunch of printfs and waits.
But the library is a PG_MAGIC_MODULE.

I tried killing it with pg_terminate_backend(pid) - but I get WARNING:   PID 
1166738497 is not a PostgreSQL server process. (Interestingly the  child 
pid=28629, which was printed in the line before)

Sure - it is intended to run independently.

Is there an internal pfork() or something similar I should use instead?
