VMMaker 4.16.8
Correct a long-standing issue in VM parameter reporting for values specified as milliseconds in the interface, but measured as microseconds internally. Adhere to the documented interface and answer the values in units of milliseconds, using Float values to supply higher precision when available from the VM. For example, a duration measured as 123456 microseconds is reported as a VM parameter value of 123.456 milliseconds. The change affects VM parameters 8, 10, 36, and 38.
