Yes, which is why I did a review of this patch in the other thread. I
had one additional request, which was to rename the GLIBC_* variables
to GLIBC_PTHREAD_* to reflect that they're used by pthreads, so that I
can do a bit of automatic namespace management in the tunables, like
building environment variable names and configuration names.
That and sorting of Versions, which Andreas has already mentioned
here.
