We could make the mapping more efficient if we used EBUSY, EINVAL, 
ENOMEM, ETIMEDOUT for the error codes, possibly with the help of a .sym 
file.  I expect that this would allow us to eliminate some of the 
wrappers and use symbol aliases instead, but it doesn't look like there 
would be many such cases.  Your call.

Thanks,
