Sleep the display OS X supports a display sleep mode that will keep your system active but turn off the display, which can be enabled using the Shift-Control-Eject hot-key sequence.

Fast user switching A final approach to locking your Mac is to use the log-in window and Apple's Fast User Switching feature enabled by default in more recent versions of OS X, but which can be enabled in the "Login Options" section of the Accounts system preferences on older versions of OS X.

If you select the log-in window then the system will keep your account active including running applications , and return you to the log-in window where you will be required to select your account and supply your password before resuming your work. I've been using this method since I posted this answer. It still works great.
