I agree, and we are still looking into it.  Unfortunately, I may need
some help, since we hit somewhat of a dead end on figuring out what is
really happening (I am not familiar with the inner workings of rtld-elf).

But I am still interested in what's planned for 7.0 in terms of the
symlinks on the threading libs in /usr/lib.  Can you fill me in on this?
 Also, is libc_r completely missing from 7.0 by now?

					Thanks, Joe
