I'm not sure that it's possible to implement this atomically. It's
probably better to leave the application to choose how the inheritance
is defined.

Example:

for handle in handles:
    os.set_inheritable(handle, True)
subprocess.call(...)
for handle in handles:
    os.set_inheritable(handle, False)

This example is safe if the application has a single thread (if a
single thread spawn new programs). Making handles non-inheritable
again may be useless.
