Co-process, also known as micro-threading, is a lightweight thread of user-state.
The co-process has its own register context and stack. When the schedule is switched, the register context and stack are saved elsewhere, and when you cut back, restore the previousThe saved register context and stack. Therefore, the process can retain the state of the last invocation (that is, a specific combination of al

Overview
The Golang is a lightweight thread in the perfectly formed, while the Golang management process is bound to involve the transition between the threads: the blocking process is switched out, and the running coprocessor is switched in. In this section, we will carefully analyze how the process is switched.

Benefits
No overhead for thread context switching
No need for atomic operation locking and synchronization overhead
Simplified programming model for easy switching control
High concurrency + high scalability + low cost
Disadvantages
The inability to take advantage of multi-core resources is essentially a single thread that does not need to use multicore to combine multiple processes to take
