title: Objective-C Blocks and Garbage Collection Enviroment
body: <p>I can't found any reference about Blocks and Garbage Collection; even the "Apple Bocks Reference" doesn't mention anithing about it (just few notes).</p>
  
  <p>I never developed using blocks in a GC enviroment and I would like to know how it works, what is supported and how much "automatic" is the whole process.</p>
  
  <p>Thanks in adv.</p>
