this will be useful for preventing resource pack sending from overloading the network.
it's not the best solution for that (since it means the RTT will limit the pack download speed), but it's easier than implementing congestion control and will work fine in most cases.
this is a pain :(
It appears the client always sorts the keys in alphabetical order due to use of std::map. However I'm not sure of the exact ordering behaviour, so it needs to be investigated.

I didn't merge the original PR because this needs to be checked for explicitly registered handlers as well as auto-detected ones from listeners.
In the future we should look into making empty slots be represented by null or a different, special item type, instead of breaking the air block for this purpose.

As discussed many years ago in #2551, no one actually knows what this property actually means. It definitely isn't the conventionally expected definition of 'solid' found in the real world, as signs are solid but flower pots are not.
In PHP 8.4, the type of `PHP_DEBUG` changes from `int` to `bool`.
See [PHP.Watch: PHP 8.4: `PHP_ZTS` and `PHP_DEBUG` constant value type changed from `int` to `bool`](https://php.watch/versions/8.4/PHP_ZTS-PHP_DEBUG-const-type-change).
This changes the constants to `ZEND_DEBUG_BUILD`, which contains the same value but as a `bool` across all PHP versions.

there's no need for the worker specialization here (isShutdown and shutdown are aliased to isJoined and join respectively), and the unstacking is not really desirable either as we previously learned with AsyncPool.
Despite the comments, there doesn't seem to be an obvious reason for these to be copy-pasted. Perhaps there was some legacy reason for this with legacy pthreads.
In fact, it looks likely that quit() will probably be able to be traitified too.
