Hi Gregory, I saw your commit here:

This basically means that in 3.2 it is mandatory to specify close_fds to avoid a DeprecationWarning. *BUT* there is no good value that works both on Windows and Linux if you redirect stdout/stderr, as shown in this bug.

So basically in 3.2 to avoid a warning, each and every usage of Popen() with a redirection should be guarded by an if that checks the platform. I don't think this is acceptable.

Have I misunderstood something? Also: can you please explain how the behaviour is going to change in 3.3? I assume that you are planning to change the default to True; but would that also cover Windows' singularity in redirection cases?
