Code Issues Activity Actions

LibThread: Post the completion callbacks to the *current* event loop

Browse source 
FilePicker was not showing thumbnails correctly because once each
thumbnail rendering BackgroundAction completed, it posted a deferred
invocation event to the *main* event loop.

Since FilePicker runs in a nested event loop, those completion
callbacks never ran until it was too late and the FilePicker was gone.
