Any good anagrams for multi-environment real-time?

The Multi-Environment Real-Time operating system was one of the earliest to be constructed using an organizational concept that later became known as a "micro-kernel". Multi-Environment Real-Time was created in the 1970s at Bell Labs, and was a spinoff of Unix. It ran on Digital Equipment Corporation PDP-11 computers. A version called Duplex Multi Environment Real Time was the operating system for the AT&T 3B20D telephone switching minicomputer; DMERT was renamed UNIX-RTR in 1982. Although it was not exactly a micro-kernel as they are today, it was a definitely not a "monolithic kernel"; it was a major step down the road to micro-kernels. MERT was an operating system which was divided up into several semi-independent components, all of which ran on a lower-level "kernel". The kernel provided only the lowest-level basic mechanisms; the other components needed for an operating system were constructed as processes which ran on top of the kernel. Inter-process communication was done with messages, event flags, shared memory and shared files.
