  I am not advocating in favor or agains't libc wrapper. And it
was causing more trouble than good, as several modules
are compiled with a mix of libc wrapper and libc calls.
  If modules depends only on libc, libm and libdl (and vendor
provided libraries) there should not exist problems, but if modules
start depending on external apis that change frequently, things can
become a mess, and this is already somewhat true now that we
don't have a single tree and single "make World".

  A user space binary only for different operating systems, is
possible (usually 2d), as well as an api that would make it easier
to write the kernel portions (usually 3d) in an easier way. But
easier said than done.
