Zlib::GzipReader should wrap the GZIPInputStream in a BufferedInputStream for 
performance

                 Key: JRUBY-4310
                 URL: http://jira.codehaus.org/browse/JRUBY-4310
             Project: JRuby
          Issue Type: Bug
    Affects Versions: JRuby 1.4
            Reporter: Wayne Meissner
            Assignee: Wayne Meissner
            Priority: Trivial
             Fix For: JRuby 1.5



java.util.zip.GZIPInputStream is not internally buffered, so every call to read 
results in a JNI call to decompress a small amount of data.

By simply wrapping the GZIPInputStream in a BufferedInputStream, the inflater 
overhead is reduced significantly.
