Calloop (used by our linux executor) was running all futures regardless
of how long they take. Unfortunaly some of our futures are rather busy
and take a while (>10ms).

Running all of them froze the editor for multiple seconds or even
minutes when opening a large project diff (git reset HEAD~2000 in
chromium for example).

Closes #ISSUE
