What did you do?

Invoking blocking syscall function with goroutine;
When the Go process invokes the C function, it occupies an independent system thread. Therefore, if the C function is invoked concurrently in the Go program and the C function has blocking operations, the Go program may continuously create new system threads. However, the Go program does not recycle system threads.
How did i do to let the Go program to recycle system threads?

@justkeepsimple sadly Go 1.13 is no longer supported. Please upgrade to Go 1.17 and let us know if you still see the problem. Thanks

The problem persists after the new version（1.17.2） is compiled and run. @davecheney

@davecheney
after invoking C function, Call the function immediately.
func KillOne() {
var wg sync.WaitGroup
wg.Add(1)

go func() {
	defer wg.Done()
	runtime.LockOSThread()
	return
}()

wg.Wait()

}
It seems to be working！

However, the Go program does not recycle system threads.

Could you show a code example? Why do you think it doesn't? Thanks.
