Revise deadlock detection
The deadlock detection mechanism of saker.build depends on the ThreadGroup API. The code itself is not really robust as lingering threads may cause the deadlock not to be noticed. Additionally, the issue #2 is also a side effect of the current mechanism.
As per https://mail.openjdk.java.net/pipermail/loom-dev/2020-July/001471.html, the intetion for the ThreadGroup API is to be deprecated over time. It also includes heavy synchronization and may not be reliable enough for proper use for deadlock detection. The solution for this is to revise the current implementation and come up with some different mechanism for deadlock detection. This may include placing additional restrictions on the build tasks.
One solution might be is to only allow waiting for other tasks on the main thread of a task. The main thread is the one that Task.run() is invoked on. This could make it easier to detect the deadlocks as only a single thread needs to be kept in check for the detection.
In order for this to work additional APIs may need to be added to allow waiting for multiple tasks at once. Existing task implementations also need to be checked and tested to be conforming.
With this solution the build will be considered as deadlocked if all running main threads are in waiting state.
This would also make the deadlock detection faster as no polling would be required, the deadlock would be detected instantaneously as the last thread enters the waiting state.
The solution would still allow retrieving task results without waiting on worker threads. E.g. getFinished should work.
Inner task threads also need to be checked for deadlock. Starting new tasks should also be constrained to the main task threads or main inner task threads.
Inner tasks will be disallowed to start new tasks as their duplication feature introduces a transient state in which deadlock is hard (or impossible?) to detect. If we'd allow inner tasks to start new tasks, then as the future duplicated inner task threads are not yet present in our representation, therefore incorrectly detecting a deadlock although new task would be started.
So to summarize, task manipulation (starting and waiting for) can only be done on the main thread of the build task. It can also be done on build clusters so that is allowed now. Inner tasks are not allowed to any of these. However, they can start new inner tasks and wait for their results.
The retrieval of inner task results are limited to task threads only, however, this may be lifted in the future. (As well with other inner task restrictions as stated above.)

Another related error in CI build, logs below.
Seems like the issue is that sometimes a waiting thread doesn't get unparked when the condition gets satisfied. At least in the below case, the stack trace shows that the thread was waiting for the ancestors (the task with "plus" identifier) to be finished. After the timeout interruption, the condition check returned successful, and the task was further executed.
