process blocking on Altix

I have an MPI application that launches another executable on rank zero via a system call. The problem is that the other MPI ranks sit at a barrier consuming cycles that I want my other executable to use. In my IRIX64 days, I used blockproc/unblockproc to put the 'extra' MPI ranks to sleep and revive them when needed. I cannot find anything similar on the Altix platform.

Do you know of any routines on the Altix that mimic the functionality of [un]blockproc?
