Description

It should be impossible to use write operation (Create, Update, Delete) inside read operation (Each).
At the moment it is possible, but this is unsafe, it can lead to traversing indexes tries and changing them at the same time. At the moment, we don't have traversing algorithms that can handle these situations. I also don't think it should be solved by changing these algorithms.

The workaround at the moment is to use ReaderWriterLock via ISynchronizedLinks.

Research direction

The issue identifies Each and Create/Update/Delete operations, with ISynchronizedLinks as the current workaround. Start by tracing how these operations interact with traversal and index code; done means writes attempted during Each are prevented and the unsafe modification case is covered by tests.
