  ### NSCoding Caveats
  
- - Encoded operations do not include any block properties. Be sure to set `completionBlock` and any other callback blocks as necessary when using `-initWithCoder:` or `NSKeyedUnarchiver`, for example.
+ - Encoded operations do not include any block or stream properties. Be sure to set `completionBlock`, `outputStream`, and any callback blocks as necessary when using `-initWithCoder:` or `NSKeyedUnarchiver`.
  - Operations are paused on `encodeWithCoder:`. If the operation was encoded while paused or still executing, its archived state will return `YES` for `isReady`. Otherwise, the state of an operation when encoding will remain unchanged.
  
  ### NSCopying Caveats
  
  - `-copy` and `-copyWithZone:` return a new operation with the `NSURLRequest` of the original. So rather than an exact copy of the operation at that particular instant, the copying mechanism returns a completely new instance, which can be useful for retrying operations.
- - Operation copies do not include `completionBlock`, but do include any other callback blocks of the original. `completionBlock` often strongly captures a reference to `self`, which, perhaps surprisingly, would otherwise point to the _original_ operation when copied.

  @warning Attempting to load a `file://` URL in iOS 4 may result in an `NSInvalidArgumentException`, caused by the connection returning `NSURLResponse` rather than `NSHTTPURLResponse`, which is the behavior as of iOS 5.
