This is normal. The above are all threads of the same application, they
don't actually eat the sum of the memory, but since they share their
memory space, "top" will show the same data for all of them.
You won't see this on x86 because I suppose debian's glibc on x86 has
NPTL support enabled (the new pthread library), which we don't have for
ppc yet. (It's available in upstream glibc, but debian's is quite
outdated).
