/**
|
|
* @brief The "standard" allocator, as per [20.4].
|
|
*
|
|
* The private _Alloc is "SGI" style. (See comments at the top
|
|
* of stl_alloc.h.)
|
|
*
|
|
* The underlying allocator behaves as follows.
|
|
* - __default_alloc_template is used via two typedefs
|
|
* - "__single_client_alloc" typedef does no locking for threads
|
|
* - "__alloc" typedef is threadsafe via the locks
|
|
* - __new_alloc is used for memory requests
|
|
*
|
|
* (See @link Allocators allocators info @endlink for more.)
