Just import subprocess at the top of your module.  If subprocess
hasn't been imported yet, it will be imported when your module is
loaded.  If it's already been imported, your module will use the
cached version that's already been imported.

In other words, it sounds like Python already does what you want.  You
don't need to do anything special.
