        Durga, the behavior of Solaris libpkcs11 is to always support 
multiple threads. So, this argument is essentially ignored then. For an 
application, it does not make a difference.

        eh, I looked into this some time ago, I think that OpenSC's engine 
supports slighly more then our engine but I can't remember what it was :( If 
you find out I would be happy to hear that.
