  20 /*  FUNCTION
  21         This function will free a slot in taskstorage
  22
  23     INPUTS
  24         The slot to free.
  25
  26     RESULT
  27         None
  28
  29     NOTES
  30         Currently no checks are performed if one is owner of the slot.
  31         This may be added in the future so one should deallocate a slot
  32         from the same task that allocated the slot.
