YES!

open("/mnt/bar", O_RDWR|O_CREAT|O_TRUNC|O_DIRECT|O_LARGEFILE, 0666) = 3
pwrite(3, "\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0"..., 4096, 4299161600) = 4096
mmap2(NULL, 2097152, PROT_READ|PROT_WRITE, MAP_SHARED, 3, 0x100200) = 0xb7c26000
pwrite(3, "\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0"..., 4096, 4301258752) = 4096
exit_group(0)                           = ?

I'll re-run my original test(s) tomorrow.
Thanks again!
