In case you want to protect two variables (or more) with the
same mutex.
For instance:
Mutex m;
synchronized(m) int next_id;
synchronized(m) Object[int] objects_by_id;
Wrap in a struct and it would be even much clearer and safer.
struct ObjectRepository {
int next_id;
Object[int] objects_by_id;
}
//or whatever that combination indicates anyway
synchronized ObjectRepository objeRepo;
I guess that'd be fine too.

That solution does not work in the general case. More
specifically any graph-like data structure. E.g a linked-lists,
trees, etc..
Think for example an insert to a shared AVL tree.
