Throwing an exception from a finalizer can cause the following fatal error: Error: async hook stack has become corrupted (actual: 2, expected: 0) 1: 0x970b5a node::InternalCallbackScope::~InternalCallbackScope() [./node] 2: 0x99dda0 node::Environment::RunTimers(uv_timer_s*) [./node] 3: 0x13d8b22 [./node] 4: 0x13dbe42 uv_run [./node] 5: 0xa57974 node::NodeMainInstance::Run() [./node] 6: 0x9dbc17 node::Start(int, char**) [./node] 7: 0x7f4965417f43 __libc_start_main [/lib64/libc.so.6] 8: 0x96f4ae _start [./node] By https://github.com/nodejs/node/issues/34341#issuecomment-658426281, calling into JS from a finalizer and/or throwing exceptions from there is not advised, because the stack may or may not be set up for JS execution. The best solution is to run the user's finalizer from a `SetImmediate()` callback.
