Interop with C is easy to code but deceptively expensive from a machine standpoint, due to correctness guarantees when you're switching from green threads to no-green-threads. It involves interacting with the go scheduler and possibly/probably blowing your cache and TLBs. And the automatic memory management is great, but the above commenter was saying that if you're going to extreme lengths to work around the automatic memory management, maybe you needed a non-GC language in the first place.
