Why not use common.mustCall? It uses essentially the same mechanism

node/test/common/index.js

Lines 428 to 429 in b85baf7

// add the exit listener only once to avoid listener leak warnings
if (mustCallChecks.length === 0) process.on('exit', runCallChecks);

The goal is to have no MakeCallback() calls coming from Node.js before the check is run, since those would also run the microtask queue. process.on('exit') would be too late for that, process.on('beforeExit') should be okay.
