	Provide an asynchronous Semaphore implementation. This is useful for synchronizing concurrent access to a shared resource.
2019-11-18	chore: refine feature flags (#1785)	Carl Lerche
	Removes dependencies between Tokio feature flags. For example, `process` should not depend on `sync` simply because it uses the `mpsc` channel. Instead, feature flags represent public APIs that become available with the feature enabled. When the feature is not enabled, the functionality is removed. If another Tokio component requires the functionality, it is stays as `pub(crate)`. The threaded scheduler is now exposed under `rt-threaded`. This feature flag only enables the threaded scheduler and does not include I/O, networking, or time. Those features must be explictly enabled. A `full` feature flag is added that enables all features. `stdin`, `stdout`, `stderr` are exposed under `io-std`. Macros are used to scope code by feature flag.
2019-11-03	test: unify MockTask and task::spawn (#1728)	Carl Lerche
	Delete `MockTask` in favor of `task::spawn`. Both are functionally equivalent.
2019-10-29	sync: move into `tokio` crate (#1705)	Carl Lerche
	A step towards collapsing Tokio sub crates into a single `tokio` crate (#1318). The sync implementation is now provided by the main `tokio` crate. Functionality can be opted out of by using the various net related feature flags.
