}bedrock.cube.data.copy - watcher creates semaphore files for child threads

[pbuncik]

Describe the bug
Watcher (main thread) creates semaphore files for child threads, which attempt to delete the semaphore files on their own. But since the files are created in scope of main thread commit, the child threads might be prone to locking issue.

To Reproduce
Running the process in parallel (pParallelThreads > 1) should reveal the issue.

Expected behavior
No locking should happen.
