Has to be a different system. The QNX I ran on could handle a bunch of

A lot of people still seem to believe that
microkernels are inherently
slow, even though fast microkernels (specifically QNX) predate the
slow ones by several years.
Wait, are we talking about the same operating system called QNX?
We had a customer at Cygnus in the 1990s (perhaps QNX itself) who wanted
us to port the GNU compilers to it. It was the slowest, buggiest system
we ever tried to run our code on. I think they claimed POSIX
compatibility; hollow laugh!
