async tasks are cool, but the usual PSA applies here:

Be careful to hold your references, because async tasks without active references will be garbage collected. I've been bitten by that in the past.

"Important

Save a reference to the result of this function, to avoid a task disappearing mid-execution. The event loop only keeps weak references to tasks. A task that isn’t referenced elsewhere may get garbage collected at any time, even before it’s done."
