Disable rainbow wheel mouse pointer?

[altjx]

Ever since I've upgraded to Mavericks when it became available, I've been in these random situations to where my mouse pointer will just turn into a rainbow wheel. I'm usually using VMware Fusion for work while this happens, but I'm never encountering anything crazy inside of the VMs I'm working with, so I'm not quite sure where the problem is.

When I reboot, all is usually fine. However, this is very annoying. My mouse has been a rainbow wheel for the last 4 hours today, and I just don't want to reboot...

Is there any way I can just disable this annoying thing? Or even figure out what it is? I can't even accurately click on things because I have no idea where the "point" of the cursor is.

EDIT: Nevermind. I just launched Disk Utility and after all these hours, the rainbow wheel just suddenly went away. This makes no sense to me right now. Now Disk Utility never fully loads. I only get a spinning wheel for that app now. Fml

That wheel indicates a freezing application, most often due to not enough RAM available for that application and the OS copying unused content of the RAM to the storage drive (HDD or SSD) to make more room in the RAM, also called "PAGING OUT".

How much RAM do you have and what does Activity Monitor > MEMORY show you in the bottom section with all the funny numbers and graphic?
Can you make a screenshot and attach it to your next post?

added:
IT might also be a sign of a dying HDD, if you use one.
Maybe once you restart again:

You can use the following applications to benchmark the speed of your HDD / SSD, to see, if it is the culprit:

• AJA System Test
• Blackmagic Disk Speed Test
• Xbench

I have 16GB of memory. Here's a screenshot of the Activity Monitor:

EDIT: Running Blackmagic Disk Speed Test atm. Looks good thus far, but I'll upload image shortly once it's complete. Thanks for your help thus far.

Not sure if this app has any plans on stopping soon, but here are the results thus far:
