I tested MS NT in 1998-2002. I was pleased by the results to run real
multi-tasking processes at that time. I ran some linux machines=20
at that time, too.

Anyway the heap walker problems in all the unix and linux systems
were very obvious in those years.=20

My conclusion at that time was people from DEC were really good in the OS.
