+ * Interface for thread local allocation. Memory obtained
+ * this way can be used by all threads, as though it were obtained
+ * from an allocator like GC_malloc. The difference is that GC_local_malloc
+ * counts the number of allocations of a given size from the current thread,
+ * and uses GC_malloc_many to perform the allocations once a threashold
+ * is exceeded. Thus far less synchronization may be needed.
+ * Allocation of known large objects should not use this interface.
+ * This interface is designed primarily for fast allocation of small
+ * objects on multiprocessors, e.g. for a JVM running on an MP server.
+ *
+ * If this file is included with GC_GCJ_SUPPORT defined, GCJ-style
+ * bitmap allocation primitives will also be included.
+ *
+ * If this file is included with GC_REDIRECT_TO_LOCAL defined, then
+ * GC_MALLOC, GC_MALLOC_ATOMIC, and possibly GC_GCJ_MALLOC will
+ * be redefined to use the thread local allocatoor.
+ *
+ * The interface is available only if the collector is built with
+ * -DTHREAD_LOCAL_ALLOC, which is currently supported only on Linux.
+ *
+ * The debugging allocators use standard, not thread-local allocation.
