hipocrite.
You're spouting nonsense. User to user means > process A in VM 1 switching to process B in VM 2.

You have angry fingers (one of my problems). You don't need a user context switch for kernel paths in a NOS kernel. In NetWare, user context switches are done in gates in the GDT with TSS descriptors, not in kernel fast paths with LAN I/O, which isn't what I was talking about.
