This differs from other igv_print* methods, it creates a well-formed and complete ideal graph xml immediately, while others accomplish their ideal graph xml when VM exists (i.e. destructor of `IdealGraphPrinter::_xx_printer`). If VM crashes before VM exit, the ideal graph xml will be ill-formed, this is fairly a common case when debugging another crash.
