	#
	#   - Random (true/false)
	#     Indicates that the caller desires random NOPs (if supported).
	#   - SaveRegisters (array)
	#     The list of registers that should not be clobbered by the NOP
	#     generator.
	#   - Badchars (string)
	#     The list of characters that should be avoided by the NOP 
	#     generator.
