I just couldn't get rid of the race condition when starting/stopping the `shareIn` Flow
Fix race condition we new lease was not yet added, but leaseCheck ran and cancelled the sourceJob despite an ongoing get() call Simplify debug flags Refactor debug flags Fix test Fix flaky test New debug flags Improve debug output Further work on SharedResource + more tests Fixed race-conditions related to fast and short lifecycles get()+close() There might still be an issue related to addChild(...).close and InternalCancellationException being thrown? Fix null sourceValue being accessed on scope cancellation

SharedResource, which is a class that manages the lifecycle of costly dependencies. These costly services are mostly Root and ADB related (launching a service in an extra process and connecting to it).Replacing RXShell (#1529) made flaws within the old
SharedResourcevisible, where we could trigger a race condition if one consumer gets a new lease, while another closes the last one.I couldn't get the
Flow.shareInlogic (on which the oldSharedResourcewas based) to work. This is custom solution which gives me finer control over the behavior.This should get us
