Well I may modify executeprocess/fpsystem to deal with stderr if that is a
missing feature (may not be possible, haven't looked into it much).

Or, get assignstream working on windows and not just unix, but that will
be a bit of a big undertaking, and again may not be possible.

mseide/msegui may also have some tips in its source code as it captures a
lot of stuff and puts it into the ide in its custom widgets that trap
outputs, actually kind of a bit like a Blackbox ComponentPascal IDE from
switzerland, but still different ;-)
