Review Comment:
   > what' rule to add or not add the nx prefix?
   
   The original idea in the naming was to create a separate (but very similar) 
namespace for functions that should be called only within the OS (or libc) vs. 
functions that can be called only from applications.
   
   Often the nx* named functions and application interface of the same name 
differ only in that the application interface performs application related 
housekeeping like setting the errno value and/or handling cancellation points, 
neither of which apply within the OS.  Then they call the corresponding nx* 
function to perform the core functionality.
   
   Lots of OS internal functions do not begin with nx*.  Is that a problem?  I 
don't think so if it impossible to confuse them with user APIs.
