You're right, it's another mmap (one in malloc.c), with
PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS. When I wrote the bug
report, I was assuming that the kernel documentation was correct (and
from that, I thought that the problem could only come from the mmap in
arena.c). Now it appears more clearly that this is a kernel problem...
