No, it's OK also for the other backends. This might make the test even
more robust.

Well, the two Tramp backends aren't such fast. That's why I use a 0.1
sec timeout for all read-event calls. Maybe we could introduce a
defconst for this, setting it to 0.02 for local backends, and to 0.1 for
remote backends.

Please install the patch; I'll test it then for the other 5 backends
next days.

Best regards, Michael.
