You could look at the implementation of system() to make sure you know exactly when it will or won't create a shell. I'm on a different platform, so my memory of that won't help you.

Furthermore, you can hide the shell so it can't run accidently! Perl uses an ENV variable to locate the shell; point it at an error instead, before the first such call.
