I think we are going to need more context. If you were able to pause net.Listen().Accept() the kernel's listen queue would eventually fill and the kernel would reject any new connection requests. And when you resumed accepting connections if enough time had elapsed those old connection requests would no longer be valid. I don't see why you need any of the three solutions you proposed. Why not simply set a flag that indicates whether new connections should be handled? If the flag is false simply accept the connection request then close the connection (or do whatever else makes sense). I read your StackOverflow question and am still perplexed what problem you are trying to solve.
