Minor typos in Ice 3.0.1 manual

[bartley]

Page 714, section 30.3 (Object Adapters), second bullet: the word existing makes the sentence a bit awkward. It currently reads:

It assists in life cycle operations so Ice objects and servants can be created and existing destroyed without race conditions.

It would probably be clearer if it instead read:

It assists in life cycle operations so Ice objects and servants can be created and destroyed without race conditions.

or, perhaps:

It assists in life cycle operations so Ice objects and servants can be created and existing ones destroyed without race conditions.

Page 737, second paragraph, last sentence: currently reads:

The code catches that exception and returns zero its stead;

but should read:

The code catches that exception and returns zero instead;
