There is currently no way of "locking" CUs. Some processing may arbitrarily
access more and more CUs, and even the previous ones. Processing may need
generally unlimited number of CUs, therefore it can reach the limit and flush
still referenced CU.
Therefore I find prepare_execute_command as the only safe place to flush any
CU.
(I may miss there exist some more strict rules than I am aware of.)
Thanks,
Jan
