Another approach:
Organize things so that the log output goes to a pipe.
Use the "tee" command to duplicate the output, one going to another 
pipe, the other going to the log file.
Your application can then read the tee'd-off pipe, automatically 
blocking when there is no more input and automatically unblocking as 
soon as new input becomes available.
