Finder's Friend X for Mac

From Finanza Real-Time:

The X version is not quite as useful as the 1.5.1 version since you can restart the finder by the force quit command. You can still quit the finder though which could be useful!
1. Have you ever had a message appear that says "Not enough memory..." yada yada yada when you don't have any applications launched? Well sometimes when you quit a program for some reason the memory that was previously being used by the program gets locked up. This means that the computer still thinks you have a program using the memory and keeps you from accessing it. Restarting the Finder can cure this problem in seconds. Once you restart the finder it will likely recognize that no programs are using said memory and will free it up.
2. Ever run processor intensive programs such as emulators (ie. Virtual PC or SNES9X) and games? Well if you don't have a spiffy new imac or a lightening fast blue and white tower and you aren't getting the performance that you want from these applications, then quitting the Finder may help improve your speed. When you quit the Finder you will notice that the finder is no longer available in the active application menu in the top right corner of the screen and you cannot simply click the desktop to make it return. I can hear you asking "How do get my Finder back?" Fear not my friend, simply quit all open applications and the Finder will return.
I offer no guarantees with this script to how much performance you will gain. I also take no responsibility for any damage it may cause. I use this script quite frequently on my own mac and have never encountered a single serious problem since its creation.
