SetImmediate allows scripts to yield to the browser, executing a given operation asynchronously, in a manner that is typically more efficient and consumes less power than the usual setTimeout(..., 0) pattern. This library provides a simple setImmediate shim.

This library is a dependency of readdirp. Even though setimmediate is packaged, patching readdirp to use it is more work.
