When properly used in place of @c my_malloc(), this can significantly
improve concurrency. Don't use this or related functions to allocate
large chunks of memory. Use for temporary storage only. The memory
will be freed automatically at the end of the statement; no explicit
code is required to prevent memory leaks.
