As discussed in http://marc.info/?t=120473411300003&r=1&w=4 I changed the
default buffer size used in Cocoon to 1 MB. This will prevent OOMEs with overly
large resources in most circumstances when the user has not configured the
buffer size. On the other hand it will hardly affect any "normal" Cocoon
pipeline rendering since 1 MB for markup is rather large. The buffer size can
still be configured to complete buffering by setting it to -1 explicitly (which
used to be the default).

> When reading a huge resource (i.e. 700MB file) the ResourceReader produces an
> overflow due to the BufferedOutputStream which is used (and forced to be used
> via AbstractReader). The BufferedOutputStream flushes only at the end (or
> when forced to), but overwrites the flush method to do nothing.
> As I don't know exactly where the BufferedOutputStream is used and what kind
> of impacts it will have to change it there I'm just going to fix the
> ResourceReader.
