In terms of ITSET, there should be one created process associated with
an inferior.  For example, there are two inferiors,

  inferior 1 -> no process,
  inferior 2 -> process 1234,

When using ITSET i1-2, we don't care about inferior 1, because there is
no process created at all.

As you pointed out blew, my work doesn't cover dynamic itset.  In this
case, when process is created and associated to inferior 1 later, I
don't have a mechanism to update itset in target side.

I am unable to handle dynamic itset so far.
