Detailed Description

An ExternalAsciiStringResource is a wrapper around an ASCII string buffer that resides outside V8's heap. Implement an ExternalAsciiStringResource to manage the life cycle of the underlying buffer. Note that the string data must be immutable and that the data must be strict (7-bit) ASCII, not Latin-1 or UTF-8, which would require special treatment internally in the engine and, in the case of UTF-8, do not allow efficient indexing. Use String::New or convert to 16 bit data for non-ASCII.
