sys.stdin has size if it is connected to a normal file, or
to some device nodes (in unixoid OS environments).  Size is
not available for terminals, pipes, etc.

I just tested with Python 1.5.2 under Linux 2.2 and got 0
for size of a terminal, but correct figures for file sizes
using redirection:

    $ python sizer.py
    0

    $ python sizer.py <sizer.py
    95
