Asyncslot eager execution and qtinter.modal

Hi!
Firstly, thanks for the awesome library!

I've noticed that asyncslot and modal might not work correctly all the time. Particularly, when modal is used in the eagerly executed part of an asyncslot.

Environment: Python 3.10.12 (Linux), PySide6 6.5.1.1, qtinter 0.11.0.
I use qtinter.using_asyncio_from_qt().

For example:

# slot is connected via asyncslot
async def on_settings_btn_clicked(self):
    dialog_coro = qtinter.modal(settings_dialog.exec)
    # this call will result in an exception
    result = await dialog_coro()

The exception:

Traceback (most recent call last):
  File "...", line 233, in on_settings_btn_clicked
    result = await dialog_coro()
  File ".../site-packages/qtinter/_modal.py", line 29, in modal_wrapper
    loop.exec_modal(modal_fn)
  File ".../site-packages/qtinter/_base_events.py", line 232, in exec_modal
    raise RuntimeError('QiBaseEventLoop.exec_modal() must be called '
RuntimeError: QiBaseEventLoop.exec_modal() must be called from a coroutine or callback

If I add await asyncio.sleep(0) just before the await of a modal, then everything works fine. Like that:

# slot is connected via asyncslot
async def on_settings_btn_clicked(self):
    dialog_coro = qtinter.modal(settings_dialog.exec)
    await asyncio.sleep(0)
    result = await dialog_coro()

Am I doing something wrong here? What is the best practice for something like this?

Types missing

Hi,
I'm confused. When I try to run the example (on macos), it already fails when importing asyncSlot and AsyncSlotRunner.
And in the sources, I can't find such types. What's happen?

The exception (and ResourceWarning) varies when certain (attribute or method) members of CustomSelector are commented out; the behavior looks random.

No exception is thrown if from PySide6 import QtCore is commented out, or if PySide6 is replaced with PyQt6.

The ResourceWarnings suggest an (unexpected) reference cycle might be introduced when PySide6.QtCore is imported.

A (proper) workaround is to close the loop after use.

System test errors

Use this issue to record errors in the "system test" step in CI testing. These test failures (except those caused by test infrastructure problem) are used to reveal bugs in the Python standard library itself.

qtinter0.8 ,@qtinter.asyncslot function can't used in QMenu??

self.contextMenu = QMenu(self)
self.actionRefresh = QAction("Refresh", self, priority=QAction.LowPriority)
self.actionRefresh.triggered.connect(self.actionRefreshHandler)
self.contextMenu.addAction(self.actionRefresh)

@qtinter.asyncslot
async def  actionRefreshHandler(self):
         pass

can you test this in example?
