[issue16548] os.system won't run any command and there is no error message when memory cannot be allocated

R. David Murray added the comment: Agree with the rejection. os.system is intended to be a minimal wrapper around the system call, as are most things in the os module, and as such mirroring the behavior of the system call (by returning -1) is less surprising than raising an exception, even th
