This example demonstrates how to create a worker Thread to do some work without affecting the main thread. This worker thread also give us an effective way to pause and resume the thread without using Thread. The major problem with Thread. Suspend is that you never know what the thread was doing when you call suspend on the thread. The thread might be in critical section or mutex which can lead to deadlock. The proper way to suspend the thread indefinitely is to use a ManualResetEvent.
A thread is defined as the execution path of a program. Each thread defines a unique flow of control. If your application involves complicated and time consuming operations, then it is often helpful to set different execution paths or threads, with each thread performing a particular job. Threads are lightweight processes.

Concurrency and Synchronization in The Racket Guide introduces threads. See Threads for basic information on the Racket thread model. See also Futures and Places. When a thread is created, it is placed into the management of the current custodian and added to the current thread group.
This creates a new thread. Once the thread is created it can be manipulated with "handle". One thing to note is that like Unix, the lower the priority value i. Priority values depend on the scheduler.
