I'm wondering if we should split the (possibly huge) char arrays in BodyContentImpl into smaller chunks of char arrays. Each chunk will be able to grow big enough to handle the usual cases efficiently (e.g. 64KB). Whenever a bigger size is needed we allocate more of these chunks from a pool. After using the BodyContentImpl we give back all chunks except for the first to the chunk pool.

This way performance should not really suffer, but the char arrays can be efficiently shrinked for apps needing generating large responses every now and then.

This could be a good idea, but performance would suffer, I think: if one request needs 100 buffers, then you'll have 100 synced operations to retrieve them from the pool (only one to put them back, hopefully ;)). It could then be cheaper to always allocate new objects.
