* qfThreadInfo queries are required in GDB 11 and 12 as these GDBs require the server to support
* threading even when there's only the possiblity for one thread to exist. In this instance,
* we have to tell GDB that there is a single active thread so it doesn't think the "thread" died.
* qsThreadInfo will always follow qfThreadInfo when we reply as we have to specify 'l' at the
* end to terminate the list.. GDB doesn't like this not happening.
