The ttymsg() function is used by programs such as talkd(8), syslogd(8),
wall(1), etc., to display the contents of a uio structure on a terminal.
ttymsg() forks and finishes in the child if the write would block after
waiting up to tmout seconds.

string is not newline-terminated. Various "normal" errors are ignored
(exclusive-use, lack of permission, etc.).
