I have a couple of powerpc bots that on occasion time out as well.  It 
doesn't happen very often and I have been trying to tweak things to 
avoid it but it is still an ongoing issue.

At least a few of the factories have the ability to override the timeout 
setting on a per-slave basis.  See the SanitizerBuildFactory and 
LLVMCMakeBuildFactory factories for instance.  Perhaps it is time to add 
this to all (or at least more) of the factories.
