    <p>This is my first attempt to play with decorators (although my code doesn't actually use the @decorate syntax), and I don't have much experience with multi-threading/multiprocessing. With that disclaimer, though, here's an attempt I made:</p> <pre><code>from multiprocessing import Lock def decorate_all(obj): lock = Lock() #you'll want to make this more robust: fnc_names = [fnctn for fnctn in dir(obj) if '__' not in fnctn] for name in fnc_names: print 'decorating ' + name fnc = getattr(obj, name) setattr(obj, name, decorate(fnc, lock)) return obj def decorate(fnctn, lock): def decorated(*args): print 'acquiring lock' lock.acquire() try: print 'calling decorated function' return fnctn(*args) finally: print 'releasing lock' lock.release() return decorated def thread_safe(superclass): lock = Lock() class Thread_Safe(superclass): def __init__(self, *args, **kwargs): super(Thread_Safe, self).__init__(*args, **kwargs) return decorate_all(Thread_Safe) &gt;&gt;&gt; thread_safe_set = thread_safe(set) decorating add decorating clear decorating copy decorating difference decorating difference_update decorating discard decorating intersection decorating intersection_update decorating isdisjoint decorating issubset decorating issuperset decorating pop decorating remove decorating symmetric_difference decorating symmetric_difference_update decorating union decorating update &gt;&gt;&gt; s = thread_safe_set() &gt;&gt;&gt; s.add(1) acquiring lock calling decorated function releasing lock &gt;&gt;&gt; s.add(4) acquiring lock calling decorated function releasing lock &gt;&gt;&gt; s.pop() acquiring lock calling decorated function releasing lock 1 &gt;&gt;&gt; s.pop() acquiring lock calling decorated function releasing lock 4 &gt;&gt;&gt; </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
