// and the return code of the failed operation.
// However, it is also documented as:
//
// "In addition to ssl and ret, SSL_get_error()
// inspects the current thread's OpenSSL error
// queue."
//
// So, if any OpenSSL operation on the main thread
// forgets to clear the error queue, those errors
// *will* leak into other things that *do* error
// checking. In our case, into Qt's SSL read callback,
// resulting in all clients being disconnected.
