Thanks again. That's a good point about changing while ($chr...) to while (defined ($chr...)). Without it, a null character will cause the logging subprocess to exit, which would be very sad.

Two minor notes about the sysread code: one would be to add some synchronizing code so the parent process can wait until first sysread is in progress. That way Perl won't eat any of the parent's output into its buffers for <DATA>. The second would be to change next unless /\s/ to next unless /\s$/ so that a burst of characters that contains a space followed by the start of the password won't be printed before the password can be removed.
