I am yet to fully understand the logic at the assertion site, just wondering in:

node/test/parallel/test-worker-eventlooputil.js

Line 107 in 3df5afb

assert.ok(idleActive(wElu) > idleActive(w2),

is wElu actually w? I ask this because w is unused in the entire section:

node/test/parallel/test-worker-eventlooputil.js

Lines 99 to 112 in 3df5afb

    
           function checkWorkerActive() { 
        
             const w = workerELU(); 
        
             metricsCh.port2.postMessage({ cmd: 'spin', dur: 50 }); 
        
             metricsCh.port2.once('message', (wElu) => { 
        
               const w2 = workerELU(w); 
        
               assert.ok(w2.active >= 50, `${w2.active} < 50`); 
        
               assert.ok(idleActive(wElu) > idleActive(w2), 
        
                         `${idleActive(wElu)} <= ${idleActive(w2)}`); 
        
               metricsCh.port2.postMessage({ cmd: 'close' }); 
        
             }); 
        
           }

looks like, at least the failing site is consistent.

This is consistently failing in CI right now. Lets mark it flaky while we figure out what is going on. Refs: nodejs#35844

The active worker check compared the time from sending message till response arrived from worker with the complete time the worker was running till it responses to the spin request. If sending back the message is slow for some reason the test fails. Adapt the test to compare the time seen inside the worker with the time read from main thread.
