Any way to query the setDefaultCluster?
This would only work immediately afterwards, right? What about a few pages of code later? Basically: if you start a parallel or snow cluster without preserving the cluster object, it will run with no way to shut it down, right? In other words, is there any easy way to accomplish what snowfall does using parallel and snow? i.e.: sfInit() sfStop() --j

To clarify: if I "forget" to store a cluster object:
myfunction <- function()
{
library("parallel")
cl <- makeCluster(2,type="PSOCK")
setDefaultCluster(cl)
return(cl)
}
myfunction()
Is there any way to stop this running cluster short of quitting out of R?
