Calling `sleep()` causes `TypeError: can't convert null to BigInt`

使用連結的 swiftwasmsleep 專案和提供的 Swift 程式碼片段重現此失敗。先追蹤 node_modules/@wasmer/wasi/lib/index.esm.js 中的 poll_oneoff，以及 entrypoint/dev.js 中從 startWasiTask 發出的呼叫。完成的標準是 sleep(1000) 在沒有 BigInt TypeError 的情況下完成，且程式印出 "After sleep()"。

Title says it. Code:

import Foundation
import JavaScriptKit

print("Before sleep()")
sleep(1000) // wasm bails out
print("After sleep()") // Never happens
