System Calls

syscall create(in object_size: usize, in fifo_length: usize, out handle: Pipe): Spawns a new pipe with create.fifo_length elements of create.object_size bytes. If create.fifo_length is 0, the pipe is synchronous and can only send data if a Read call is active. Otherwise, up to create.fifo_length elements can be stored in a FIFO.
syscall get_fifo_length(in handle: Pipe, out length: usize): Returns the length of the pipe-internal FIFO in elements.
syscall get_object_size(in handle: Pipe, out size: usize): Returns the size of the objects stored in the pipe.

async_call Write(in handle: Pipe, in data: bytestr, in stride: usize, in mode: PipeMode, out count: usize): Writes elements from Write.data into the given pipe.
async_call Read(in handle: Pipe, in buffer: bytebuf, in stride: usize, in mode: PipeMode, out count: usize): Reads elements from a pipe into Read.buffer.
