Interesting. V2_OS [1] does not support multitasking.
This our point of view on this: We will not change the architecture of the kernel to allow it to multitask since this will affect the whole system even when it is not multitasking and that's not the way me ment it.

It could be argued that MS- DOS (MicroSoft Disk Operating System) was the Fastest Proprietary 80x86 Based Operating System around yet no one I know would use it anymore. Okay, besides being a 16-bit clone of an 8-bit OS, it didn't allow multitasking either yet people went to great lengths to include it.
It's beginning to look like that those who do not study the history of MS-DOS (MicroSoft Disk Operating System) are condemed to reimpliment it—poorly.
And MS-DOS wasn't all that great to begin with.
