Funny how we didn't think it was a big problem on PDP-11 UNIX.  The
"small systems" you mention today have more inherent power than those
PDP-11s; the problem seems to be that convenient means of exploiting
the power are not being provided.

Real-time has nothing to do with it.

Only if the application is deliberately constrained to POSIX implementations.
I don't use fork() gratuitously.

Feel free.
