 you pass it to knows it can execute the code inside it by calling.run() on it.
When you send a Runnable object to the Handler, that Runnable is executed in the Handler's Thread.
In simple terms it's probably sufficient to explain it this way: If you want to supply a Handler with some work to do on its own Thread, then you have to supply that piece of code inside an object. Now, the object you supply to the Handler has to implement some kind of interface so that the Handler knows what methods to call in that object to make it do the stuff it needs to do. In basic terms that's what the Runnable interface does: it is mandatory for an object that implements Runnable to implement the run() method. 

 Q:

How to prevent lxml.etree.HTML( data ) from crashing on certain type of data?

I'm running etree.HTML( data ) like below for lots of different data contents. With a specific data conent, however, lxml.etree.HTML will not parse it, but go into an infinite loop and consume 100% CPU.
Does anyone know exactly what in this data below that can be causing this?  And more importantly, how can I prevent this from happening on an infinite number of random, broken data?

Edit: Turns out this is a bug with lxml version 2.7.8 and below (at
  least). Updated to lxml 2.9.0, and bug is gone.

Edit: I know this constitutes an infinite loop, but that's not the bad behaviour I'm getting. It runs fine (as an infinite loop) with a healthy data content. With unhealthy data content, like below, what happens is that the loop will STOP and RAM will start filling up and when it's full, all CPU goes into WAIT state.  See this question for the original debug.

 When you send a Runnable aim to the animal trainer, that Runnable is executed in the Handler's Thread. 
 In simple term it's credibly sufficient to explain it this way: If you want to issue a Handler with some work to make on its own Thread, then you have to supply that objet d'art of code inside an object. Now, the aim you supply to the Handler has to implement some kind of interface so that the Handler knows what methods to call in that object to lay down it do the stuff it need to do. In basic terms that's what the Runnable interface does: it is compulsory for an object that enforce Runnable to implement the run () method.
