IMHO you should carefully check the os.system() call's return value.

you could replace the os.system() call with the following one
which I know for sure works :

def myexec(commandline) :
    import popen2
    process = popen2.Popen3(commandline, capturestderr=1)
    retcode = process.wait()
    output = process.fromchild.read()
    errors = process.childerr.read()
    
and check retcode according to the W* functions in 
http://www.python.org/doc/current/lib/os-process.html#os-process

of course depending on the retcode you may or may not have
to read the child's stdout or stderr.

hth.
