Ahh, so it is.  I misread the parameters to open() in strace.

Incidentally, on the Linux environment on my Lenovo Chromebook 
Duet (a rather resource-constrained environment that runs under 
multiple layers of emulation), I found nncp-caller was using about 
3.5% of CPU while maintaining an otherwise-idle TCP connection, 
and less otherwise.  I wonder if we could have a paremeter to 
decrease the rescan interval there?
