Currently, this option can be TRUE or FALSE only. If TRUE, all CPUs are used, which can cause all the memory to be used up and system swapping out.

Attempting to pass an numeric value produces an error:

Running prepInputs for: CC VTM
Error in (function (nnodes = getOption("mc.cores", 2L), ...)  : 
  'nnodes' must be >= 1

even though getOption(".mc.cores") returns 4 (and even if it were NULL the default is 2)
