Please join in the discussion of principles for when there should be 
wrappers for a system call, and work on driving that discussion to 
consensus (e.g. seeking further views, analysing the common ground between 
views expressed, looking at issues with different approaches for system 
call wrappers, looking at how different suggestions from the discussion 
would handle various existing system calls that currently lack wrappers 
(or for that matter, those that currently have wrappers)).
