Old info; AmigaOS had(has) very little support for fork() as all of the OS
ran(runs) in the same memory space (under special circumstanses there was a
vfork() though; see geekgadgets below. In addition to the "lightweight
threads" that were/are standard).
bash, and might I guess - most of those above, are/is littered with fork()
calls IIUC (I have not looked).
I'm not too sure if fork()-use is to be considered "state of the art" and
thus make a containing project be considered "modern".
Without really knowing I would have thought better of such projects if
they'd used pthreads or some such instead. [ This statement is based on
"basic OS theory" taught at university college in Sweden at least ]
IMO your "modern shell" statement above is about the same as was stating
"DOS compatible" a number of years ago. [BG: 640K ought to be enough...]
There was(is) a pdksh available though. It was(is) included in the
"geekgadgets" unix emulation project.
Yes, geekgadgets was the same for AmigaOS as cygwin currently is for
