I just realized that I missed to reply.  Of course we would like to have
a posix_spawn.  However, I'm not sure you can simply put a posix_spawn
over our exec/spawn implementation.  This would require a redesign of
the exec/spawn code in the first place, isn't it?

Did you already have a look into the current implementation?  I don't
know about your POC implementation and if it's plain Windows or requires
Cygwin.

Last but not least, code contributions require a copyright assignment:
