I am afraid you will have to add the triphase user to the xenomai group
and pass the xeno_nucleus.xenomai_gid option to the kernel. Or else
rewrite the vfork + exec yourself dropping root privileges after the fork.
The reason is that the native api assumes that if you fork in a xenomai
program, chances are you will want to use the native api in the child
program.
