With RC3, the behavior is not so desirable to me.
I have a build ongoing, and I did "Close other document tabs" in windows.
After a short time, it asked me to force terminate the build, to which I answered no.
The build is still going, but the other document tabs are still there.
When I try again (repeatedly) to close other document tabs, nothing happens, no prompt to force terminate, and other document tabs do not close.
The desirable behavior is that when I close other document tabs while the build is ongoing, that I am not prompted to terminate my build, my build keeps going, and the other tabs close.
