+FAIL: Timed out waiting for notifyDone to be called
 Test WorkerGlobalScope.close() method. Will print PASS multiple times, followed by DONE.

 Test 1: Call close() in the worker, then enter infinite loop. From the Worker object side, call terminate(). Verify the loop is terminated.
 PASS: workerThreadCount = 0
 PASS: Worker thread created and closed, received message: closed
-PASS: Worker exited after terminate() terminated the infinite loop.
-Test 2: post 2 messages to a MessagePort into the worker. port.onmessage handler inside the worker will call close(). Verify that the second onmessage was not executed.

-PASS: MessagePort multiple message test, received message: echo_ping1
-PASS: MessagePort messages were not delivered asfter close().

Maybe they fail on other ports too, but I can't test on any port different from Qt.

and fast/workers/worker-lifecycle.html fails if you run only 
fast/workers tests instead of all tests.

+info:
-------
- fast/workers/storage/interrupt-database.html passes if you run only 
  this test, but it is extremely slow, the runtime is 12-18 seconds
- fast/workers/worker-close-more.html fails always (if you run only
  this test or only fast/workers tests or all tests)
- fast/workers/worker-lifecycle.html passes if you run only this test
  or all tests, but fails if you run fast/workers tests

The bug is same on 32 and on 64 bit LLINT C loop.

ping?

I can reproduce the fast/workers/worker-close-more.html and fast/workers/worker-lifecycle.html notifyDone() timeouts on an ASM llint build with JIT & DFG disabled.  This is not a C++ llint specific issue.

[Csaba Osztrogonác]

Status report:
- fast/workers/storage/interrupt-database.html: still extremely slow
- fast/workers/worker-close-more.html: still fails always
- fast/workers/worker-lifecycle.html: it passes now

Is there any plan to fix LLInt? Or can we live with this buggy LLInt?

I see these same failures when running the tests with a debug build using the JIT as well.  This tells me that this isn't a matter of correctness, but perhaps of performance.  Alternatively, it may be because the tests have timeouts that are too short.

This issue is currently low on my priority list.  You're welcome to debug it and provide suggestions for improvement or a patch though.
