xct::McsWwBlock* foedus::soc::ThreadMemoryAnchors::mcs_ww_lock_memories_

void* foedus::soc::ThreadMemoryAnchors::task_input_memory_

Input buffer for an impersonated task.

Always 512kb (so far, make it configurable later).

thread::ThreadControlBlock* foedus::soc::ThreadMemoryAnchors::thread_memory_

Status and synchronization mechanism for impersonation of this thread.

Always 32kb (a bit large mainly due to the size of FixedErrorStack).
