To illustrate my point, below is what the memory map for the exact same
binary looks like on 2.6. The VMA in question is the one between
0xa8000 and 0xba000, which 2.2. kernels don't zero-allocate.
00001000-000a8000 rwxp 00000000 03:07 62988 /tmp/prog
000a8000-000ba000 rwxp 00000000 00:00 0
000ba000-000bf000 rwxp 000a7000 03:07 62988 /tmp/prog
bffff000-c0000000 rwxp 00000000 00:00 0
ffffe000-fffff000 ---p 00000000 00:00 0
