Thanks all.
I found the answer, rather easily.
To make a system call and wait for it, do:
subprocess.Popen([r"/sw/bin/gzip","-d","access_log.4.gz"]).wait();

yeah, that's a really relevant criticism when we're talking about a
module that contains one function and one class
Yeah, I agree. The Python documentation just merey describes what

Well, if you use a function of the "popen" family, you get some kind of
return value from the su
suppose i'm calling two system processes, one to unzip, and one to
“tail” to get the last line. How can i determine when the first
process is done?
Example:
subprocess.Popen([r"/sw/bin/gzip","-d","access_log.4.gz"]);
last_line=subprocess.Popen([r"/usr/bin/tail","-n 1","access_log.4"],
