   I prefer the `ScalaFutures` as it expresses the intention clearly and keeps 
timeout handling consistent across usages with decent defaults (15 secs). 
Further it opens up the possibility of [scaling][1] the timeouts as per 
environment in a global way i.e. increasing the scaling factor for slow CI 
setups. Currently various test have there own specific  timeouts and which need 
to be tweaked as and when we see such failures. 
   
    Much of scalatest is anyway magical!
