   Reading this thread really hurts. Can we please have less guessing and more 
rootcausing? 
   
   How should a unit test be related to ccache, considering it's not a compile 
task? Why should network or disk io be a problem in a suite of tests? Even if 
there was limited io, I've never heard of a case where your request gets 
terminated or put into a deadlock in case of hitting the limit. AWS always uses 
throttling.
   
   MXNet is a highly parallel piece of software. If something in tests was 
about to get stuck intermittently, my first thought would be to actually look 
into my software under test and not just plain out blame the infrastructure. 
You wouldn't blame a processor in case your program prints a wrong value, 
right? So please, for the sake of the entire project, can we stop the guessing 
game and stop turning of production systems as a measure to apparently resolve 
or root cause an issue?
