[Vlasov Roman via Digitalmars-d-learn]

I have the quite computer with 2 GB RAM. At compilation with dub 
and dmd of small project this pair eating about 1.4~1.5 GB RAM. I 
solve this probleb by connecting swap partition, but it calls 
some freezes + it take ~10% of swap, and after compilation swap 
not released. At switching off swap as result we get ~200 MB of 
"dead data" in RAM, which can be released by rebooting. How i can 
resolve it?
