I'm *sure* it has little-to-no value in a "resource-rich" environment
(e.g., most places where UN*X variants are deployed).  OTOH, SoC-based
systems (typically resource-starved) win each time you can save a byte!

I was hoping I could build on a FOSS platform and leave much of the products'
support/evolution to "others".  Building on a proprietary RTOS makes that
impractical.  :-/
