Chapter 16. Reusing Immortal Memory

• Using Fixed-Object Allocators

• Recycling RT Threads

• Recycling Async Event Handlers

Prevent immortal memory leaks with this rule:

Do not allocate an immortal object from code that is executed more than once in the life of the application.

And the corollary:

Try to create all immortal objects in static initializers.

These restrictions rule out actual dynamic creation of immortal objects, but they do not prevent dynamic use of immortal objects. This is the motivation for reuse of immortal objects.
