No, we abuse them too much already.
I was thinking that the vDSO could have a mecanism for retreiving infos,
maybe based on name.
int __kernel_query_config(const char *tag, void *buffer, int size);
Or something like that and we define a bunch of them in a header... Now
the problem is to get glibc to re-export that to apps...
Ben.
