Summary:
Recursively calling runTask is not supported, as the inner call will no-op since we're already executing the eventloop.

Currently errors are not correctly propagated, but this at least makes it so that we don't attempt to schedule the task either, which could lead to incorrect assumptions being made.

Add scheduleTask and runWorkLoop to public API (#48284)
358fd38
Summary:
Pull Request resolved: #48284
Changelog: [internal]
We recently prevented tasks that run via `runTask` to synchronously call `runTask` because the execution is synchronous and we can't nest tasks in the event loop (D67107664 / #48235).
This adds `scheduleTask` to schedule tasks (also within tasks) with the right expectations (the task will not run synchronously on that call but at the right time).
It also adds `runWorkLoop` so we can run scheduled tasks if they're not scheduled from an already running task.

Summary:
Recursively calling runTask is not supported, as the inner call will no-op since we're already executing the eventloop.
Currently errors are not correctly propagated, but this at least makes it so that we don't attempt to schedule the task either, which could lead to incorrect assumptions being made.

Add scheduleTask and runWorkLoop to public API (#48284)
358fd38
Summary:
Pull Request resolved: #48284
Changelog: [internal]
We recently prevented tasks that run via `runTask` to synchronously call `runTask` because the execution is synchronous and we can't nest tasks in the event loop (D67107664 / #48235).
This adds `scheduleTask` to schedule tasks (also within tasks) with the right expectations (the task will not run synchronously on that call but at the right time).
It also adds `runWorkLoop` so we can run scheduled tasks if they're not scheduled from an already running task.
