Thank you !

It's more a general issue with app_posix.py, but I think that it should
avoid these costly "import os" inside application-level functions.  You
already have the posix module imported (see the start of app_posix.py),
so you can return posix.waitpid(-1, 0).  The same comment applies to
other places too, e.g. popenfile.close().

A bientot,
