    I'm not sure it makes sense to convert um, the implementation uses
    strncpy(), and that should use the libc implementation, which is tuned
    for the actual hardware that the binary is running on, so performance
    wise that might be better.

    OTOH, maybe this is all in the noise given the huge syscall overhead in
    um, so maybe unifying it would make more sense.
