Can the combined output be > intermingled? If you just send the output to a file, you've no way of knowing exactly when it will be output, or whether it will be buffered before writing. You can mitigate this a bit by making every output line have a sequence and process identifier--the PID and date in seconds would work--so you could separate the streams later. If you really would like to get output in sequence, write to a pipe, and have a reader process drain the pipe to a logfile. It's pretty easy; look at "mknod" with the 'p' option, or "mkfifo". I'd still suggest tagging each output line with an identifier and sequence number.
