I see no recent patches for this test.  It is certainly not too many
global objects as that would only occur in a multiprocessing
configuration.

Is the BSP creating any other tasks?  The tests only configure the
minimum resources they require.

It is possible that it is a driver somewhere that is
allocating a task and it is not accounted for.
