26BUGS
27
28Threads - Currenly this module isn't threadsafe as it can't clone an open layer.
29flush() doesn't really flush, just empty the buffer
30
31TODO
32
33Lots:
34
35Check that concatenating to files works. Add a way of reading multiple
36contactenated gzip files.
37Test more
38Add an open method so that things we don't like (read/write opens) are faulted
39early (ie before a file is created on disk) and so that we add "b" flag to
40the open for the layer below.
41Test more
42Rewrite flush to really flush, and write a PerlIOGzip_write() rather than
43rely on PerlIOBuf_write, which calls flush() to empty the buffer each time.
44Test more
45Cope with crlf systems. Should this layer turn off crlf on the layer below
46and turn it on on itself?
47Cope with utf8. Should the utf8 flag be hiked above us?
48Test more
49Worry about threads.
50Writing headers with fancy stuff (filename, comment, extra info, header crc)
51What to about the "TEXT" flag in the gzip header
52Test more
