I don't doubt for a second that the author observed the behaviour he describes, because the FrontEnd is a GUI program, and like any GUI program, if it is badly designed, it can suffer from all sorts of race hazards that don't always reproduce on other machines, even though they may reproduce easily on one particular machine with one particular user. For example, every key down and key up event gets fed into a GUI program, and the timing, and hence the way that these are interspersed with other messages may depend on the human operator and hardware factors.
I think WRI should put a lot of effort into providing a logging mechanism for the FE that can record enough information to pinpoint what is going on in these situations, and then fix them.
To me, the FE has never been completely stable since version 6.0 came out.
