Javaw.exe (The MC Process) Is supposed to close upon exit of the game.

Instead of the Java process for minecraft (Javaw.exe) Closing, it continues to consume RAM and cpu usage. It only seems to affect players with a 64 bit Windows 7 Enviroment. I have tried to kill the process with Command prompt, Task manager, and scripting a program to kill the java process. None have worked. The only way to destroy these processes is to reboot the computer, but this can be time consuming.

Steps to Reproduce:
1. Open minecraft for 5 minutes.
2. Close minecraft.
3.Check task manager for the javaw program. IF you have the glitch, your Javaw.exe will be unkillable.
