But the nice thing now is that all the forked processes log also on
stdout/stderr, so if I launch the parent in the shell I get

DEBUG -> csim_flow.worker[18447]: Moving the log file
/user/sim/tests/batch_pdump_records/running/2012_12_11_13_4_10.log to
/user/sim/tests/batch_pdump_records/processed/2012_12_11_13_4_10.log

DEBUG -> csim_flow.area_manager[19410]: No new logs found in
/user/sim/tests/batch_pdump_records

where in [] I have the PID of the process.
In this suggested way I should use some other files as standard output
and error, but for that I already have the logging module that logs
in the right place..
