Blocking APIs may be inefficient because you hold a thread idle while waiting on the network. Threads are expensive because they have both a memory overhead and a context-switching overhead.

 *  Fix: Don't drop headers of healthy streams that raced with `GOAWAY` frames.
    This bug would cause HTTP/2 streams to occasional hang when the connection

// GLOSSARY: Here are a few terms used in this file to describe Named types:
//  - We say that a Named type is "instantiated" if it has been constructed by
//    instantiating a generic named type with type arguments.
//  - We say that a Named type is "declared" if it corresponds to a type
//    declaration in the source. Instantiated named types correspond to a type
