This is what I needed to know. thanks. I should have looked harder but
my tinker time on this is limited. I do not yet have my toolchain
completely done yet but I should be able to test this setting. BTW, I
did get it partially working with certain forms of fork (vfork
implementation swapped in) but as was said and as I knew, vfork is
quite an different beast but does the trick in some cases.

Now to figure out if I can slim it down anymore than using the right
compiler flags.

Thanks,
Brian.
