Really? So the fact that my access_log.gz file is still standing at 20 bytes 
and never seems to get anything is not do with BUFSIZ not being reached 
then? (since you say that apache sends a flush)

Hum .. so a CustomLog "|/usr/bin/gzip >> acccess.gz" would need to create 8K 
of data before anything would be written?

And assuming gzip compresses that incoming data 10:1 I need about 80K of log 
lines before anything gets written to file?
