Alexander, do you have any ideas about this one?  It seems to have gotten worse recently, so was wondering if it was related to your cache storage panel changes.

Congratulations, you're our top actual and still-enabled intermittent. Your prize is an overly-detailed skip-if, since there's only been one win7 debug, all the rest have been opt.

While I was looking at bug 1229272, I found this possible improvement...

Stop using CPOW when creating indexed DB in storage tests.

The change in clear() call prevents some warning messages.
And I believe the change in call to setup() fixes this intermittent.
But I'm never sure about the intermittents being really fixed now...

Until a test has run when the try servers are under high load we never really know... chaos mode helps a lot though.

Mike, can you find anybody to carry on the torch here? This is almost a permafailure on Win 7 debug. If you need someone to push to Try during the the weekend, let me know.

I believe that Alex's change fixes this.

Try seems to say it is being fixed, I launched some new runs.
But there is a suspicious intermittent:
TEST-UNEXPECTED-FAIL | leakcheck | default process: 792 bytes leaked (CEnumFormatEtc, CondVar, LazyIdleThread, Mutex, nsDataObj, ...)

But it seems to be bug 1222979.
fx-team is closed, but I'll try to push this patch once it reopens.
