To Artifact [fa426ec1c8]:

• File unix/tclUnixNotfy.c — part of check-in [2d07e770af] at 2017-04-26 14:06:21 on branch tip-458-experiment — Experiment, does this work? Still to be tested: Eliminate variable triggerPipeVal/eventFdVal (just use 'char dummy'), and just read/write 1 byte to triggerEventFd in stead of 8. Experiment failed: eventfd's always should be read/written 8 bytes. (user: jan.nijtmans size: 15040)
