After rewriting the engine to allocate less gc memory, gdc is 
faster then ldc again.

- In a slightly unfair benchmark I had an 3.5x performance 
advantage over sqlite.
   (unfair, because I don't parse SQL and just extract the colums 
raw)
    yet at the and of the day, this is how SQLite is meant to be 
used.
    As a convenient data-storage.
more news :

Write support is coming!
After that is finished let's see by how much I can beat sqlite 
dong bulk inserts.
