OSX : High Idle wake-ups and CPU usage

[tcolar]

[tcolar]

It seems after inactivity it does down as it should for goed-wde but not as much for goed-termbox and even much less for goed-tcell ... hum .... all just have a "." listing view open.

Using top is more direct and reports similar findings
top -stats pid,command,cpu,idlew,power -o power -d

1. It seems the 16ms ticker in actionbus is partly to blame, maybe i can use a blockign channel instead.

2. It's much much worst with tcell than the other backends, the tcell inputloop seems to blame.

Now fixed internally in goed, however it still occurs with the tcell front-end, must be an issue in tcell itself (upstream)

See gdamore/tcell#129

Applied a fix in a fork of tcell for the time being.

Now fixed in mainline tcell
