The second argument to writeToFileHandle is supposed to address that:

writeToFileHandle( $fileHandle [, $seekable] )

    Write a zip archive to a file handle. Return AZ_OK on success. The
    optional second arg tells whether or not to try to seek backwards to
    re-write headers.

    ...

    If you pass a file handle that is not seekable (like if you're writing
    to a pipe or a socket), pass a false second argument:

    ...

Thomas, are you sure the actual code in question is passing a false value
as the second argument?
