Well, spaning of a subprocess in an operating system independend manner is
nontrivial - e.g. on AmigaOS it is almost impossible to port programms using
fork() without greater code changes. That is one thing I loved about kaffe -
it doesn't use fork()... :-)

However, as long as the subprocess does not need its own address space
(I don't think a DNS lookup process needs its own address space..), that is
it does not use the same global and static variables as the main process,
preferably no global variables at all, creating a subprocess should be
managable in a portable way.

Just another two cents...
