+ // coordinated across C compilations and Rust compilations. Before we
+ // compile anything we make sure to wait until we acquire a token.
+ //
+ // Note that this jobserver is cached globally so we only used one per
+ // process and only worry about creating it once.
+ //
+ // * Next we use a raw `thread::spawn` per thread to actually compile
+ // objects in parallel. We only actually spawn a thread after we've
+ // acquired a token to perform some work
+ //
+ // * Finally though we want to keep the dependencies of this crate
+ // pretty light, so we avoid using a safe abstraction like `rayon` and
+ // instead rely on some bits of `unsafe` code. We know that this stack
+ // frame persists while everything is compiling so we use all the
+ // stack-allocated objects without cloning/reallocating. We use a
+ // transmute to `State` with a `'static` lifetime to persist
+ // everything we need across the boundary, and the join-on-drop
+ // semantics of `JoinOnDrop` should ensure that our stack frame is
+ // alive while threads are alive.
+ //
+ // With all that in mind we compile all objects in a loop here, after we
+ // acquire the appropriate tokens, Once all objects have been compiled
+ // we join on all the threads and propagate the results of compilation.
