>From the stack trace, it looks like this is an about to suspend in atomic mode
error that was hit in the process of trying to report another error by writing that error to DrRacket's window. I don't see what has put the VM in atomic mode, but it looks like the original error was a "port is closed" error via `read-line`. Maybe the `read-line` call was reached through `http-conn-sendrecv!`, since I see one in the `net/http-client` library. Does a "port is closed" error sound familiar, especially during the time that you used `http-conn-sendrecv!`? Can you reconstruct the version that used `http-conn-sendrecv!`?
