Thanks for catching this. I'll fix this in v5. In terms of
platforms
that support dup3 vs dup2, I'm assuming the following preprocessor
checks will do what we need:
#if defined(__linux__) || defined(__CYGWIN__)
dup3(fd, monfd->fd, O_CLOEXEC)
#else
dup2()+fcntl(F_GETFD/F_SETFD)
#endif
Checking for dup3() in configure might be the better option. It's not
like it has been there forever, even on Linux.
