test case is fail case.

Code reviewed and tested with 3.0 Galaxy Tab 10.1 and 2.3.3 DroidX. On Rhino, 2.3.3 device (DroidX), if you click very fast, after 1-2 cycles, then you won't be able to close window 2. It says: unable to close, window is not open, even though it is open.

Hieu, do we know if this is a regression introduced with this fix or existing behavior? I suspect that is a separate issue that does not need to hold up the acceptance of this PR. Please advise.

[hieupham007]

That I'm not sure, this could indicate a deeper issue (we won't know until further investigation). In other words, this fix is just a band-aid. It's up to you and Bill.

Hieu, Can you reproduce the behavior with the same test case on master?

@hieupham007 @DizzyMonkey @billdawson I was able to confirm the error that Hieu saw on my Galaxy Nexus, but this appears to be a completely unrelated issue that's related to timing and the internal window states in window.js

Other than that, I'm fine with merging this as is.

I've created a new bug for the behavior Hieu found here:
https://jira.appcelerator.org/browse/TIMOB-7705

@hieupham007 Can you test this against 1.8.0.1 and make sure this isn't a regression?

Functional review accepted, tested on both V8 and Rhino
