If you've compiled the magic sysrq support among the kernel hacking functions, Alt+SysRq+U mounts all filesystems read-only, and from there you're safe. Else, you can unmount filesystems or "mount -o remount,ro" them. In the latter case, you might need to go into single-user-mode to be able to remount your root file system read-only. However, if your system is not doing anything else, journaling file systems and a "sync" issued before the experiment should be just fine (mounting read-only is the sure bet, though).
