Szabolcs, Chung-Lin,
Which tunables namespace should we use for the dynamic loader?
glibc.dl.* (currently proposed by Szabolcs for dl_nns, and surplus static tls).
glibc.rtld.* (currently proposed by Chung-Lin for dynamic_sort=N changes).
dl = dynamic loader/linker
rtld = runtime loader/linker
We have Solaris precedence for using rtld.
We have MacOS precedence for using DL_*
My slight inclination would be to use glibc.rtld.* for everything.
I find rtld immediately identifiable as a loader-related tunable.
While glibc.dl.* might be libdl.so, or ld.so, or something else.
Thoughts?

Cheers,
Carlos.

rtld sounds good to me, i will change it in my patch.
(i used dl.nns because i tried to model the existing
DL_NNS macro and we haven't had other rtld tunables)
