Not particularly. If the machines and/or OS arch are reliable in the first place it's not a problem to spread builds across more machines. But in reality, it's not very reliable, so 1) adding machines just means babysitting additional crashes, and 2) if emulation is used instead of real machines, then you're dealing with both OS bugs and emulator bugs.
