From source file org.apache.tez.common.AsyncDispatcherConcurrent.java

/**
 * A dispatcher that can schedule events concurrently. Uses a fixed size threadpool

 * on the same thread in the threadpool. This can be used to prevent concurrency issues
 * for events that may not be independently processed.
