THRIFT-3564: potential core dump in TQTcpServer
TQTcpServer: it's not allowed to delete the sender of a Qt signal
(QTcpSocket) while executing one of its slots. This could happen in
TQTcpServer::beginDecode() in case an exception occurred. Ensured, that
deletion is deferred in all cases.

> It's undefined behaviour, if a Qt object (sender) get's deleted while
> executing on of it's slots. This can happen in case an exception occurs in
> TQTcpServer::beginDecode() as the call to ctxMap_.erase() will delete the
> sender of the Qt signal.
