I've never seen >the idle time affected by output. Hmmm. systat uses getch() to read from the terminal and there's a bug somewhere that results in the atime being set for unsuccessful reads. I think getch() does a blocking read and the read gets terminated by a SIGALRM. ufsspec_read() is more broken than ufs_readwrite(). It sets the IN_ACCESS flag at the start of the read, long before successful completion, so the access time may be stamped soon after but not upon sucessful completion. ufs_readwrite() only sets it upon both unsuccessful and successful completions.
