Depends on your programs and RAM. If the program you try to switch to (or, say, part of X or your window manage) is swapped out for some reason, then yes, changing focus may cause said program to hang until it can swap the data in. Usually that's a small fraction of a second, but if your IDE bus is waiting for a burn, then it could be the duration of the burn.
