You misunderstand mempools if you make such claims.

There is in fact guarantee that objects will be returned to mempool. In 
the past I reviewed device mapper thoroughly to make sure that it can make 
forward progress even if there is no available memory.

I don't know what should I tell you if you keep on repeating the same 
false claim over and over again. Should I explain mempool oprerations to 
you in detail? Or will you find it on your own?
