Hanging process gives weird effects

[annejan]

When a process hangs (for example git interaction) the whole app starts behaving badly.

When going to config for example the key pair generation dialog pops up because the list of keys can't be retrieved.

This breaks down to two things.

A) The "wizard" needs to not jump to action on errors like this.

B) Process scheduling should behave in a more sane way and possibly also kill "hanging" processes.

Can't happen anymore. .

Not adding killing of things here . . for obvious reasons
