/********************* Arena code follows *****************************
 * ArenaPools are like heaps.  The memory in them consists of large blocks,
 * called arenas, which are allocated from the/a system heap.  Inside an
 * ArenaPool, the arenas are organized as if they were in a stack.  Newly
 * allocated arenas are "pushed" on that stack.  When you attempt to
 * allocate memory from an ArenaPool, the code first looks to see if there
 * is enough unused space in the top arena on the stack to satisfy your
 * request, and if so, your request is satisfied from that arena.
 * Otherwise, a new arena is allocated (or taken from NSPR's list of freed
 * arenas) and pushed on to the stack.  The new arena is always big enough
 * to satisfy the request, and is also at least a minimum size that is
 * established at the time that the ArenaPool is created.
 *
 * The ArenaMark function returns the address of a marker in the arena at
 * the top of the arena stack.  It is the address of the place in the arena
 * on the top of the arena stack from which the next block of memory will
 * be allocated.  Each ArenaPool has its own separate stack, and hence
 * marks are only relevant to the ArenaPool from which they are gotten.
 * Marks may be nested.  That is, a thread can get a mark, and then get
 * another mark.
 *
 * It is intended that all the marks in an ArenaPool may only be owned by a
 * single thread.  In DEBUG builds, this is enforced.  In non-DEBUG builds,
 * it is not.  In DEBUG builds, when a thread gets a mark from an
 * ArenaPool, no other thread may acquire a mark in that ArenaPool while
 * that mark exists, that is, until that mark is unmarked or released.
 * Therefore, it is important that every mark be unmarked or released when
 * the creating thread has no further need for exclusive ownership of the
 * right to manage the ArenaPool.
 *
 * The ArenaUnmark function discards the ArenaMark at the address given,
 * and all marks nested inside that mark (that is, acquired from that same
 * ArenaPool while that mark existed).   It is an error for a thread other
 * than the mark's creator to try to unmark it.  When a thread has unmarked
 * all its marks from an ArenaPool, then another thread is able to set
 * marks in that ArenaPool.  ArenaUnmark does not deallocate (or "pop") any
 * memory allocated from the ArenaPool since the mark was created.
 *
 * ArenaRelease "pops" the stack back to the mark, deallocating all the
 * memory allocated from the arenas in the ArenaPool since that mark was
 * created, and removing any arenas from the ArenaPool that have no
 * remaining active allocations when that is done.  It implicitly releases
 * any marks nested inside the mark being explicitly released.  It is the
 * only operation, other than destroying the arenapool, that potentially
 * reduces the number of arenas on the stack.  Otherwise, the stack grows
 * until the arenapool is destroyed, at which point all the arenas are
 * freed or returned to a "free arena list", depending on their sizes.
