Every node cleans its memory-pool from old unconfirmed transactions (usually small transfers with zero-fees).
The difference is that some nodes keep such transactions for several days, Eligius does not keep zero-fee low-priority transactions at all.
OK than but why when i tried to push one of those transactions eligius rejected them (int -22) But this time it was a success i got this but why it rejected it before if you say that they don't keep this kind of transactions at all

You have to find not a relaying node, but a miner which uses "replace-by-fee" patch.
I do not know about such miners, but this is allowed by bitcoin network and bitcoin protocol.
As far as I know, biggest mining pools do not use this techinque.
Where to find these miners?
Does it allow me double-spend those tx's and if so how?
