if I (manually) start glib-full, will that mean glib-quick will also not 
run until glib-full is completely done? (basicly, that is what I want. 
regardless of the order in which builds start, I want only one at a 
certain point in time).

The above 'feeders'/'watchers' configuration looks like glib-full is not 
a feeder for the lock, so it can never block the start of glib-quick?

Based on that syntax, I would probably need to write:

BuildmasterConfig['interlocks'] = [ ("glib-lock", 
["glib-quick","glib-full"], ["glib-full","glib-quick"]) ]

But this might introduce a circular trigger (one one build starts, it 
will never stop building again)
