Hey David,

I guess you're looking for a preemptive timeout. I guess an alarm signal
and PHP's async signal handling will be your best bet here.

In case you're looking for a cooperative timeout, https://amphp.org/ and
it's `Amp\Promise\timeout()` / `TimeoutCancellationToken` might be helpful.

Best,
Niklas
