Have you tried the "-unbuffered" for your logdest (i.e. the file you
log to)? I got all the messages when I switched output to unbuffered.

The problem seems to be that interpreters are buffering and they have
their own handle on the log file -> they overwrite each other if
channels are not flushed, even in a non-multithreaded environment.

Can you please check if you get all messages? Please note that it is
also not very transparent if you have more than one child (i.e. apache
processes) serving requests. It's kind of difficult to manually follow
if you have all the expected messages...
