difference between os.fdopen and builtin open

[Dave Angel]

You've already hit the most important difference:  os.open() lets you 
share files between processes, while the built-in doesn't have any 
control of that type.

Another distinction is that fdopen() can be used to get a file object 
from a fd handle, which may be obtained some other way.  For example 
stdout or stderr.
