select is definitely how I would do it, for several key reasons:

  1. It is architecturally uncomplicated:   the process is actually doing only one thing at a time, even though it is unpredictable what it might do next.
  2. You never have to worry about things being incomplete ... about accidentally sending someone a partial-message that you haven’t finished reading yet.
  3. You can easily prioritize what it is doing, according to the business requirement.
  4. Messy timing issues are generally avoided completely.

The program itself is really a dispatcher, connected to everything else with nice, flexible pipes and sockets.   It goes to sleep, wakes up with a “honey-do list,” does its chores in whatever sequence it best sees fit, then goes back to sleep again.   As long as none of these things take a significant time to actually do, esp. relative to the others, it all works great.

[Tux]: None work for me. My dead key is AltGr (right Alt)
[Tux]: And I just tested, neither do other Tk apps :) (95% of my Tk Apps is either just monitoring (no input) or input of just numbers). Something to investigate then
[choroba]: Maybe something like this?
[choroba]: I vaguely remember we had problems with dead keys in Tk at $work - 2, but I forgot all the details
[choroba]: but it was worse on MSWin than on Linux
[choroba]: (and OSX didn't exist yet)
[choroba]: Also, I'd try starting the App with the US layout and switch to the dead keys layout later
