// Bug 1572988: Make a bunch of nursery ropes and flatten them with oomTest.

// The goal is to get an OOM while flattening that makes registering the

// string's malloc buffer with the nursery fail, triggering an assertion when

// it gets tenured.

var N = 1000; // This failed most of the time on my linux64 box.

// But it can time out on the slower machines.
