[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.

          Hm. As you say, due to no barriers this doesn't actually make any semantic
          change. But ok, if you think it makes the code clearer, it doesn't hurt
          anything, so I'll push it to 10.1.
