   details of the gzip'ped file. To explain: gzip-format files can be made up
   of one or more components (called "members" in the gzip docs for some reason).
   Most files, those you create by doing 'gzip filename' contain only a single
   member. Multiple member files are created when you concatenate multiple gzip'ped
   files, as in 'gzip -c <input >>logfile.gz". Andreas sent me the file in question,
   and it's made up of many members -- 378, to be precise, with most being a
   few hundred bytes long. The internal _read() method only returns the contents
   of a single member at a time, assuming that following members will be read
   by subsequent calls to _read(). [...]
