how to keep stty sane after piping strace to vim?

this makes vim madness: $strace -o >(vim -; stty sane) file.out; stty sane I have typed stty sane in processed substitution as well as in next command but none of them did their job. Once i piped the strace command to vim, then the vim no longer behaves normaly (I know vim can only accepts stdin and strace gives output to stderr, but then what is the -o flag for?) any help?
