9 * \brief Implements GFS session logic.
11 * Frontend server logic.
13 * This code receives incoming APDUs, and handles client requests by means
16 * Some of the code is getting quite involved, compared to simpler servers -
17 * primarily because it is asynchronous both in the communication with
18 * the user and the backend. We think the complexity will pay off in
19 * the form of greater flexibility when more asynchronous facilities
22 * Memory management has become somewhat involved. In the simple case, where
23 * only one PDU is pending at a time, it will simply reuse the same memory,
24 * once it has found its working size. When we enable multiple concurrent
25 * operations, perhaps even with multiple parallel calls to the backend, it
26 * will maintain a pool of buffers for encoding and decoding, trying to
27 * minimize memory allocation/deallocation during normal operation.
