Dumb APR_BUCKET_BUFF_SIZE question

[Rasmus Lerdorf]

Why is it hardcoded to be 8000?  It would seem like you could easily be 
unlucky and just miss the cutoff and end up with a 6000 byte heap bucket 
followed by a 3000 byte transient bucket, for example, as a result of 3 
3000 byte ap_rwrites.  For that particular case it might be quite 
beneficial to increase APR_BUCKET_BUFF_SIZE to 9000 which would suggest 
that it might be something that should be configurable.
