If you want to minimize porting efforts in the long run, I would
suggest to implement the POSIX functions, rather than the BSD functions.
  * Lots of applications have been ported to run on Linux, and use
    the POSIX API to that effect.
  * POSIX is a standard that has even some dark corner-cases fledged
    out. Like you said here:

  * Test suites exist that you can use to validate your implementation
    (even if the implementation, as for Threos, is closed-source).
