It have a program that collects output from o/s commands by forking a child process and reading its stdout/stderr seperately via a pipe. The duration and output of each exec() may not exceed a certain threshold, otherwise the exec'd child gets killed and the next system command gets run.
I have code that does this _slowly_ - maybe since I'm not buffering the reads from the pipe, but handling each line of output in terms of measuring size/duration. I cannot think of any other way of enforcing time/size thresholds on the child process...
I'm hoping an enlightened monk would have a clever trick for something like this?
1. Child process' stdout and stderr must be processed in seperate handles.
2. exec'd child cannot run for longer than xx secs
3. exec child's stdout and stderr must not exceed x lines/size
