// Hack: This is the fix for a horrible data race that I have not been able to figure out in quite some time.
// It appears to be happening when the Go HTTP code reads from the socket when closing the request (i.e. AFTER
// this function returns), and causes a data race with the ResponseWriter. Locking wlock here silences the
// data race detector. See https://github.com/binwiederhier/ntfy/issues/338#issuecomment-1163425889.
