The subb instruction added to the IA-32 assembler is not used as dec_b ended up being used instead.

There is a mesurable difference.

When starting JS profiling under Chromium, a map from function addresses to function names is created. During it, for sourceful scripts, an attempt to access script source is made. This can cause a crash, if a source is an external string, which already has been disposed. We had a similar problem in the past with DebugGetLoadedScripts.

it is a strange API and unused anyway.

When we roll this to Chrome, we'll need a small chrome patch
to fix Chrome's usage of the API.

So if the caller does something like:
while(!IdleNotification())
it could spin forever if v8 were not initialized.

I'd like to further remove the is_high_priority flag,
because it is not in use. Mads - is there any reason
not to remove it?

In DOM bindings in many cases the string would be externalized immediately.  For other cases
I am going to add explicit flattening.  Overall, it looks like if user wants to flat string
before writing, it should be an explicit method invocation (going to add TryFlattenIfNotFlat
into public V8 API).

1. Change the AST node type CallNew to be a subclass of Expression
   rather than Call.  It's not really a call but it just happens to
   have the same fields.

2. Change our error reporting for invalid left-hand sides in for-in
   statements, pre- and postfix count expressions, and assignments.
   Before we signaled a syntax error at compile time *unless* the LHS
   was a function call or 'new' expression, in which case we signaled
   a reference error at runtime.  Now we signal a reference error at
   runtime in all cases.  This matches the JSC behavior in Safari 4.
