After 7/8ths of a good night's sleep I realise this is an insanely 
stupid question, or at least one for which RTFM would have been an 
justifiable answer. The answer is in the dlopen man page. It would seen 
dlopen calls anything with the __attribute__((constructor)) attribute to 
initialise the module, and that there is a destructor as well. This is 
common for me: I figure things out just as I send an email to the list. 
Perhaps this helps someone else as well some day.
