Hello, I'm working on an application that executes scripts from untrusted users. These scripts are expected to define a certain function that we will pull out and run many times.
I have implemented a watchdog thread that ensures that no single function call takes too long (if it does, I assume there is an infinite loop in the function). Now I am trying to limit memory usage. I investigated various approaches with setrlimit and ResourceConstraints::ConfigureDefaults but those both leave the program in a bad state when it runs out of memory. Instead, I would like to occasionally use `GetHeapStatistics` to inspect the heap and error out if it has grown too large. My question is this: is it required to acquire a v8:Locker lock before using GetHeapStatistics? I am passing a pointer to my isolate to the watchdog script so that it can call v8:TerminateExecution if necessary, which is explicitly allowed in the documentation. The documentation for Locker says that a lock must be acquired to access handles or object pointers, but it's not clear if it is required for GetHeapStatistics.
