The DECB that you issue CHECK against contains an actual embedded ECB at
offset +0. There is an implied WAIT inside CHECK, but you can certainly
inspect the POST bit yourself and/or WAIT on the ECB yourself using
whatever mechanisms you have available (such as placing its address into
a larger WAIT list). Once the WAIT has been satisfied, you still need to
issue CHECK, but it runs immediately without suspending...
