Let me guess.
Windows doesn't have fstat, right?
So we need yet another libCom routine, perhaps epicsIsSocket()?

Jeff's reply is correct, but doesn't really deal with the problem
discovered by Dennis since it is stdout which is causing the
problem and stdout does not have 'close-on-exec' set.
I propose that on startup caRepeater check stdin/stdout/stderr and
if fstat(fileno(fp))reveals that the stream is a socket that the
stream be closed and reopened to /dev/null. This precludes running
caRepeater in a pipeline, but I'm not sure that's really that much
of a problem.
