Are you forgetting that system returns a combination of the return status code together with the signal number with which the code was run ?

Probably worth investigating $! - as suggested in ...Return value of -1 indicates a failure to start the program or an error of the wait(2) system call (inspect $! for the reason)...

A user level that continues to overstate my experience :-))
