A bit of a historical note on this: in the late 80s and 90s there was
an effort called "iBCS" to make a unified ABI for Intel-based unices.
I believe a common syscall layer was part of it. It was abandoned
after everybody realized that the Linux syscall ABI _was_, for all
practical purposes, the unified ABI they wanted.
