That is not technically possible. A truly concurrent GC has heavy 
penalty. People probably think of "Concurrent GC" has Microsoft 
calls one of the .NET GCs, which is "mostly concurrent".

The first step is get a precise GC. That should give a 
significant performance boost already. Everything else should 
probably build on this.
