[PATCH] parallel threads resizing - potential race condition to access freed memory

Details

    Description

      pool->threads is freed before being reassigned the new pool.

      Although not really a memory barrier I though it prudent to keep the pool thread count to be the lower of the old/new thread list before the new threads is allocated.
