That would raise the issue of compatibility. Probing each symbol
separately is much easier than trying to extend the struct.  What
exactly _is_ the impact of making the dynamic symtab a few entries
bigger?
Does compatibility really matter? I thought you need exactly matching libpthread and libthread_db versions anyway. I suppose we could even compile the offsets into libthread_db.
I assume that for compatibility across multiple versions, we will need something like Infinity. 

Thanks,
