Not so easy to check either - I'm using the standard Debian Woody packages 
for both those libraries. Is there a way to tell from the library itsself?

A strings on the library shows symbols like pthread_mutex_lock and 
pthread_mutex_unlock showing. Is that a good sign?
But I don't see any symbols like these showing in the libssl library.
