I'm sorry I didn't specify earlier, this is a box running Linux
(gentoo distribution) with:

Linux Kernel 2.4.20
glibc 2.2.5
gcc 2.95.3
python 2.2.3

The fragment of the strace output is the following, it's
between I 
press the final '\n' and the response '0\n' appears:

write(1, "\n", 1)                       = 1
rt_sigprocmask(SIG_BLOCK, [INT], [32], 8) = 0
ioctl(0, 0x8024540a, {B38400 opost isig icanon echo ...}) = 0
rt_sigprocmask(SIG_SETMASK, [32], NULL, 8) = 0
rt_sigaction(SIGINT, {0x700486f8, [], 0}, {0x700486f8, [],
0}, 0x701431c8, 8) = 0
rt_sigaction(SIGTERM, {SIG_DFL}, {0x700486f8, [], 0},
0x701431c8, 8) = 0
rt_sigaction(SIGQUIT, {SIG_DFL}, {0x700486f8, [], 0},
0x701431c8, 8) = 0
rt_sigaction(SIGALRM, {SIG_DFL}, {0x700486f8, [], 0},
0x701431c8, 8) = 0
rt_sigaction(SIGTSTP, {SIG_DFL}, {0x700486f8, [], 0},
0x701431c8, 8) = 0
rt_sigaction(SIGTTOU, {SIG_DFL}, {0x700486f8, [], 0},
0x701431c8, 8) = 0
rt_sigaction(SIGTTIN, {SIG_DFL}, {0x700486f8, [], 0},
0x701431c8, 8) = 0
rt_sigaction(SIGWINCH, {SIG_DFL}, {0x700486f8, [], 0},
0x701431c8, 8) = 0
rt_sigaction(SIGINT, NULL, {0x700486f8, [], 0}, 0, 8) = 0
rt_sigaction(SIGINT, {0x700486f8, [], 0}, NULL, 0x701431c8,
8) = 0
nfssvc(0)                               = 0
write(1, "0\n", 2)                      = 2

On x86 the fcntl64() syscall happens right before the write().

I don't think the bug is present in earlier versions of
Python because I
remember this used to work fine before the upgrade, however
I can't
pinpoint the exact release this started to show up.

Let me know if you need additional info or want me to do
some tests.
