The program is a PAM module. It is loaded through dlopen from non 
threaded programs (sendmail, dovecot). This is fine and worked fine
prior 6.0 since the PAM module does not use threads. 

Your anlysis leads us to consider pthread stuff in libgobject being 
a bug. I am not sure it is fair that the limitation of our implementation
dictates the functuionnalities third parties may fold into their libraries.

IMO the bug here is NetBSD enforcing a petty rule that breaks software,
fix nothing, and has no workaround (yet).
