Details

http://jsbin.com/gugacasuci/edit?html,output or the test in bug 1291257 are examples of cases where at some point js engine ends up calling JSRuntime::requestInterrupt even though 
there is already pending interrupt (interrupt_ == true).
However, JSRuntime::handleInterrupt never gets called.
Explicitly calling JS_RequestInterruptCallback in C++ forces the interrupt callback to get called, but in this case there really shouldn't be need for that.
Ok, I didn't know JSAutoRequest has the side effect to control interrupts.
I thought JSEngine would just call interrupt callback anyhow, and that is why xpconnect has the
timestamps updated when a new task starts and ends.
