Sometimes my ISP's DNS server doesn't behave and requests are just left to time out. This takes at least 5 minutes. When this happens during cvs operations the UI is frozen because some cvs operations are still being done on swing thread. I just got this, but can't attach a detailed stack dump as the problem also caused my whole pc to ultimately freeze up too for some reason, but I did note down the following approximate stack trace by hand that shows the important part: <resolving host name calls here> ... AddFilesOperation.login() (AddFilesOperation:27) CommandCVSHandler.login() (CommandCVSHandler:72) CVSOperationExecutor$4.run() (CVSOperationExecutor:176) LaterInvocator$1.run() (LaterInvocator:1) LaterInvocator.? (LaterInvocator:21) java.awt.InvocationEvent.dispatch() EventQueue.dispatchEvent() IdeEventQueue.c() (IdeEventQueue:180) Please fix this as it is an ongoing pain for us remote workers.
