copySendRight()
Create another send right from a given send right.
Declaration
func copySendRight() throws -> Mach.Port<Mach.SendRight>Discussion
This does not affect the makeSendCount of the receive right.
If the send right being copied has become a dead name, meaning the receiving side has been deallocated, then copySendRight() will throw a Mach.PortRightError.deadName error.
