How about to set correct headers and make the images cached on user side instead of wasting memchached resources? If you are serving tons of thumbs multiple times I bet that the traffic will be bigger problem than the time it took for these images to be read from disk.
Check this post -> http://ilian.i-n-i.org/caching-web-sites-and-web-applications/ there you can see which headers you need to set to tell the client browser to cache a resource.
