Check out the queuing used by the test suite. It stores the callbacks in an
array and normally executes them immediatly. But if one choose to block the
queue, it stops executing and must be resumed later.
It's basically no more then a more advanced "store the functions in a list and
call them one after the other in a loop", but maybe it's just what you need.
