I won't speak to the patch, but I was just able to run a server with 16 
meg of memory and go through the steps mentioned in that email with no 
problem, and I have, in the past, added caching to my own applications 
with servers running on only 32 meg of memory. So, I don't think that 
you're necessarily running into an absolute limit of 64 meg at the low 

Your problems may be related to the allocation model that memcached 
uses, with different blocks/sizes, but again, I don't know a lot about 
the application, so I can't say for sure what exactly is happening.
