Hi,
thanks a for your help... but... I still have doubt on the "cleaness" of

Every bug is also a fact ( ;-) ). In my opinion writing not ordered lines
is not so nice, instead of logging arrival rate, apache2 tracks the completion
rates but with the arrival timestamp instead of the completion timestamp;
this is not so clean...

Sorting in reasonable time is not so easy for a "real" http log file (unless
you have a cray supercomputing system... ;-) )
