we currently have 166 builds competing to build on 6 build executors
(I think).  The majority of these are non Hadoop-related builds, so
are actually competing for just 4 of those executors, 2 executors per
machine on 2 VMs.  There's a good chance many of the problems stem
from load.

maybe _not_ suck? ;)

Would you prefer if we gathered more evidence first?
