key collisions

hi, mark,
I'm having the same problem with key collisions with the python  
binding, and I was wondering if you've made any progress.  I haven't  
been able to reproduce the problem in a test, but in production,  
we'll encounter the problem all of a sudden after a while (the only  
"solution" so far is to restart memcached).  The server returns the  
wrong value for the requested key.  Not only that, but if you try a  
get_many for key 'foo', you may get a response that has key 'bar' and  
its value.
Since I haven't been able to reproduce this behavior in a test, I  
don't yet know if it's the python binding or memcached itself.
Does anyone have any ideas?
