Ubuntu, Kubuntu, Xubuntu The recently released 10.04 version of Ubuntu is the third Long Term Support (LTS) version Canonical has released. I installed this new version on four of my laptops (2 netbooks, 1 normal laptop, 1 portable desktop replacement), and here's my impression of it.

The 32-bit Windows API on DOS-Windows 95/98/ME is built on top of the 16-bit Windows kernel. Much of the functionality of the 32-bit API DLLs (kernel32.dll, user32.dll, gdi32.dll, advapi32.dll, and so forth) is provided by thunking from 32-bit to 16-bit and calling into the 16-bit Windows kernel, grabbing a global mutual exclusion semaphore known as "Win16Mutex" (that prevents multiple threads from executing in the 16-bit Windows kernel concurrently) for the duration.

Pre-emptive multitasking was only for 32 bit code. 16 bit programs were common and forced the system to multitask cooperatively. They also shared their own address space.
