To alternatives come to my mind.
1. You could write all data to the error log with ap_log_rerror.
2. You could write your data into notes with the notes api and the log
these note with %{notename}n together with the pid and other interesting
data in a special custom log.
http://httpd.apache.org/docs/2.0/mod/mod_log_config.html#formats
To learn about notes read about ap_register_request_note,
ap_get_request_note in http_core.h. I have used them once, see
http://www.heute-morgen.de/modules/mod_delay/mod_delay.c for a simple
example.
