With the JTAG interface, it is possible to stall the processor between

calls of this function (but not during upcalls). In which case we return

immediately.

@todo Is it possible (or desirable) to permit JTAG activity during upcalls,
|
|
in which case we could stall mid-run.
|

|
@todo Should the JTAG functionality require enabling?
