alex	aca7eb1165	comm: introduce a simpler way to read/write this builds on top of the main read and write fn, setting up a global structure to allow module users imply comm.pipeWrite(msg) and comm.pipeRead() without providing an allocator or reader/writer on each call. the advantage is simplification in the gui functions because they don't have access to an allocator or the nd process read/write pipe. disadvantage is in testing because it requires a global, "before all tests" setup. at the moment, only ngui is modified to use the new pipeRead/Write. the daemon would suffer too many changes, especially in tests, due to the global state.	12 months ago
