The pool bucket must be able to be easily morphed to a heap bucket if the pool gets cleaned up before all references are destroyed. This <a class="el" href="structapr__bucket__heap.html">apr_bucket_heap</a> structure is populated automatically when the pool gets cleaned up, and subsequent calls to pool_read() will result in the <a class="el" href="structapr__bucket.html">apr_bucket</a> in question being morphed into a regular heap bucket. (To avoid having to do many extra refcount manipulations and b->data manipulations, the <a class="el" href="structapr__bucket__pool.html">apr_bucket_pool</a> struct actually *contains* the <a class="el" href="structapr__bucket__heap.html">apr_bucket_heap</a> struct that it will become as its first element; the two share their <a class="el" href="structapr__bucket__refcount.html">apr_bucket_refcount</a> members.)
