When you do "strace /bin/ls" n your desktop, you will notice the
following syscall at that position:

set_thread_area({entry_number:-1 -> 6, base_addr:0xb7d92700,
limit:1048575, seg_32bit:1, contents:0, read_exec_only:0,
limit_in_pages:1, seg_not_present:0, useable:1}) = 0

Maybe the strace on the FR needs an update?
