Unpacking a zipfile containing a large number of files with mc is a
really bad idea. For example, a 5245 file zip with 199 subdirectories
took unzip about 34 seconds to unpack. mc took over 16 minutes.
Why? Because it ran over 5245 uzip processes, one after the other.
Stick to using it to inspect zipfiles and perhaps unzipping just the
odd file or two.
