Singleton pattern - Does early binding (with static variables involved) diminish the need of mutex locks?

c++, design-patterns, java, singleton, thread-safety

Solution

I think they are referring to creating the Singleton instance before starting/creating any threads, thus alleviating the need for synchronization at creation.

EDIT: adding info about C++ and static variables

In C++, static variables are also initialized before execution like David Harkness mentions for Java. One issue with this in C++ can be in embedded environments where calls to malloc/new cant be performed until after the system is initialized, in which case using a Singleton static initializer could be problematic.
