generate_error() isn't thus tagged, and it should not be, because it
does return when ERR or IOSTAT are set.

As for Janne's comment:  I don't have benchmarks, but I think this is of
the "can't hurt, may help" category.

However, if it is the consensus to forget about this patch, that's fine
with me :-)
