OH sorry. it seems has some wrong in my demo code. it should import "crypto/tls". So Close() is in crypto/tls/conn.go. And i found it blocked in "c.handshakeMutex.Lock()". I suspect that someone goroutine blocked in "c.sendAlert(alertCloseNotify)", case it`s an network IO, and i didn`t setDeadLine(). But i want to hold the Close() by self timer, than is it a wrong usage?
