[webkit-dev] Atomic Strings and static vars

[Eric Seidel]

Correct.  The AtomicString hash won't be initialized by the time the  
constructor is called on a static AtomicString.

Thats why you see AtomicString::init(() and HTMLNames::init(), etc.

See HTMLNames.cpp to see how we get around this (placement new).
