	From the help file...

"""
class zipfile.ZipFile(file[, mode[, compression[, allowZip64]]]) 
Open a ZIP file, where file can be either a path to a file (a string) or a
file-like object.
"""

	I'd interpret that to mean that it tends to work with an on-disk file.
If you've given it a file name for the archive it likely is not building a
memory image and writing it all only when closed.


"""
ZipFile.write(filename[, arcname[, compress_type]]) 
Write the file named filename to the archive, giving it the archive name
arcname (by default, this will be the same as filename, but without a drive
letter and with leading path separators removed).
"""

	I'll admit it is not clear if the individual file is first compressed
in memory and then appended to disk file (I'm not that up on the internals
of ZIP files; a true TAR file is just a concatenation of uncompressed
files; .tar.gz indicates that the concatenated file is subsequently
compressed).
