[R] snow::makeCluster on Windows hangs

[Prof Brian Ripley]

You failed to mention this about contributed package 'snow' (and a long 
obsolete version of R: see the postin guide).  That version of R has 
package 'parallel' which would be preferred.   But it looks like you did 
not manually start the workers (and I am not sure why you would want to 
do that).
