For this approach I wrote some code to simplify this: http://www.knitter.ch/src/gunixsignal/ But the other approach with the flag is not bad too. The only advantage of the pipe compared with the flag is that the pipe won't miss a Signal while the flag may miss a signal. (if you send two signal within your 100ms interval you don't know if there was more than one).
