as i said, you have to remember only recent uploads because we dont 
want to test the source we arnt downloading from. a client should also 
remember only some sources which downloads most asked chunks in 
comparison with other chunks of a file (this imply stats on chunk 
uploads).
another way is to implement a "inform me if you upload this chunk" 
message. in that case, you would have to remember those who asks, but 
it would consume less memory, and after having sent him several other 
sources, you can forget it, as he have other sources to get the info.

anyhow, this wont be implemented in mldonkey, and as i'm not in touch 
with emule devs, i wont suggest it to them.
