/**
 * One directional virtual descriptor, with bounded producer backpressure.
 *
 * The read end belongs to the scope that opened it, which closes it, and the
 * reader streams still open (`readers`, held weakly), when its command ends;
 * no reader closes it, so a function can read one substitution twice. Readers
 * take turns a chunk at a time, so they split the stream, and a ranged read
 * leaves the rest of its chunk to the next. A reader whose signal fires while
 * it waits leaves that chunk to the next reader. Mirrors Python's DevicePipe.
