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)

Checking for dup3() in configure might be the better option. It's not
like it has been there forever, even on Linux.


Ah, thanks. It looks like support is already there and I can just check:
#if defined(CONFIG_DUP3)
