Andrew,

you need to save a reference to the write stream, the GZipWriteStream will
write into.  This should work

| buffer writer |
writer := GZipWriteStream on: (buffer := WriteStream on: (ByteArray new)).
writer nextPutAll: stuff.
writer close.
buffer contents

See also FileList>>compressFile for an example (available in 2.7)
