I expect his opinions on the GC to reflect the implementations he's used, not ours.

Any implementation strategy is based on tradeoffs. D's are:

1. To run in mixed language instances, must work with C code with a frictionless 
interface.

2. To coexist peacefully with code that extensively use other allocation strategies

3. To have zero parasitic overhead

The requirements of Go and Java are quite different, which drives their 
different strategies.
