// Don't include wasm.js in timeout tests: when wasm isn't supported, it will

// quit(0) which will cause the test to fail.

// Note: this test triggers an interrupt and then iloops in Wasm code. If the

// interrupt fires before the Wasm code is compiled, the test relies on the

// JS interrupt check in onEnterFrame to catch it. Warp/Ion code however can

// elide the combined interrupt/overrecursion check in simple leaf functions.

// Long story short, set the Warp threshold to a non-zero value to prevent

// intermittent timeouts with --ion-eager.
