I've seen similar behaviour from the SolarWinds Application Performance 
Monitoring product: it explicitly allocates a TTY when ssh'ing to a 
monitored host (every 5 bloody minutes...) just in case any commands 
would otherwise fail.  Hence bash thinks it's a human logging in and 
records the commands.  Blech.
