Within one thread, synchronization contexts may be nested which can naturally happen in a hierarchy of method calls.
The nested synchronization contexts may also acquire overlapping sets of artifacts/metadatas as long as the following
conditions are met. If the outer-most context holding a particular resource is exclusive, that resource can be
reacquired in any nested context. If however the outer-most context is shared, the resource may only be reacquired by
nested contexts if these are also shared.
A synchronization context is meant to be utilized by only one thread and as such is not thread-safe.
Note that the level of actual synchronization is subject to the implementation and might range from OS-wide to none.
