This function eventually calls Allocate_Processor and while tracing with gdb, everything is going as I planned, i.e. the correct node is getting preempted and the caller to it is getting allocated the CPU. But, the test fails here, because eventually the heir is not changed.

The heir should get set (in SMP scheduling) by call to
_Thread_Dispatch_update_heir() from Allocate_Processor. Probably you
need to look at your allocate_processor hook.
