Control When Thread Alloc Retains Memory For Future Use


It should be faster, even when num_thread is equal to one, for thread_alloc to hold onto memory. Calling hold_memory with value equal to true, instructs thread_alloc to hold onto memory, and put it in the available pool, after each call to return_memory .

If value is true, thread_alloc with hold onto memory for future quick use. If it is false, future calls to return_memory will return the corresponding memory to the system. By default (when hold_memory has not been called) thread_alloc does not hold onto memory.

Memory that is being held by thread_alloc can be returned to the system using free_available .
