Thank you for reply!
The problem of such 'controller' Trigger is that you can loose one of
builder(actually slave) and such Trigger will wait it.
And block other possible build.
Situation is much better with Dependent - no problem to loose or overload
one builder(slave), it will block nothing.
But here I've mentioned another problem, that Dependent runs sometimes
before all builds finished. I think it's connected with 'mergeRequests'
property. Have not understand yet..
Anyway I've made combination of 'controller' Trigger and Dependent and
monitoring how it works..
