Consider an environment in which there is a one-to-one mapping between user-level threads and kernel-level threads that allows one or more threads within a process to issue blocking system calls while other threads continue to run. Explain why this model can make multi-threaded programs run faster than their single-threaded counterparts on a uniprocessor computer.
