CP/M programs will run on MP/M and TurboDOS which are multitasking and 
multi-user operating systems, MP/M first being available in 1978.

Emulators may run on DOS, Windows and Unix/Linux.

CP/M-86 programs will run on Concurrent-CP/M-86, Concurrent-DOS, 
DR-Multiuser-DOS, System Manager and Real/32.  These are a series of 
pre-emptive mult-tasking, multiuser operating systems starting in 1981 and 
still being developed as Real/32.

CP/M-86 may be run under DOSEMU on Linux.

A program written for CP/M-86 can run on a multi-tasking system and need 
not 'lock out' anything.

Compared to DRI operating systems it took Microsoft 15 years to drag itself 
out of the 'stoneage'  and come up with a pre-emptive multitasking OS.
