[fpc-pascal]No wait execution and redirection of stdin and stdout

[Peter H.M. Brooks]

Sadly I need to do development under msdros.

I would like to do two things that are nice and easy under linux, but don't
seem that easy in the underworld.

- Firstly I'd like to launch a program with no wait and then check for its
completion later.

- Secondly, when launching a program I'd like to redirect its stdin and
stdout equivalents so that I can write to it and read from it while it is
executing - clearly I need to be able to do the above first!

- I'd also like to be able to send signals to programs that I have launched
to terminate them or establish their current state.

The linux unit doesn't work under msdros, so any advice on the above would
be welcome!
