    Remove mentions of ENOSYS added in d97e44784bb5
    
    aio(4) is a hard requirement in the kernel as of f3215338ef82. The
    scenario that the patch was submitted for is no longer possible.
    
    This isn't a straight up revert since the previous change also addressed
    some minor issues.
