That's not entirely true of NT. However, all that went to hell when
they started opening up the kernel-space to various parts of the GUI for
the sake of speed for the gamers.
If you can dig up some docs about how NT was -supposed- to be, you'd be
impressed that such a system could come out of Redmond:
* Support for multiple runtime environments, fully-implemented in
userland so that you could run Unix, OS/2, Win32, Win16, or DOS
applications on the same kernel with the ability for the user to add
more just by installing a driver.
* Wholly portable and written in C and Pascal, unlike the x86 assembly
speed hacks in Windows 9x.
* A microkernel design so that the same kernel-mode software can
support vastly different systems (SGI x86 vs Compaq SMP vs "white
box" PC) just by swapping in a HAL driver.
* Impossible for userland code (including drivers) to crash the kernel
or the system (because memory access and MMU frobbing happens in the
HAL). In fact, there're only two special cases:
a) Any driver for any essential part of the console crashes and
cannot be restarted, the system performs a graceful shutdown.
b) Any portion of the storage system for the system partition
crashes, the system forces a graceful crash with memory dump.
* Kernel-deep threads, fifos, sockets, etc. all with enough memory
protection to keep a bug in, say, WinSock from stomping on the
It's a really nice system, but the concessions they started making in
NT4 have turned it to shit. We had systems at JJT that we -beat to
hell- day in, day out, with SAS, VC++, Oracle, and whatever else,
running on crap hardware, and they Would Not Crash. Ever.
In fact, the only two times I saw NT crash there:
1) I'd just installed some memory in my workstation and hadn't done
it right. I bumped my desk and the memory hopped off the bus. :)
2) After upgrading to NT4. :(
