Detailed Description

Tells background work (the duration preload) that a Browse is being answered, so the background work gives way: a Browse of a big SAF folder needs the processor and the system's Binder threads for itself, and the preload asks the same document provider for every file.

Nothing is blocked for good: a waiter gives up after a limit, and a Browse never waits for the background work.

Usage: the Browse calls enter() and, in a finally block, exit(); the background work calls awaitIdle(long) between two files. No Android classes.
