This can be avoid by
- building every package twice (also useful for integrity check)
- randomize build order
- timedout jobs
It's not a trivial problem but imho distribute tools advantages
(price, scalability, availability ...) should be seriously considered.
Has a single build system in a single datacenter should be a single
point of failure.
