! NonStop Process pair testing.
!
! - 1 NonStop Server, 1 client test driver
!
! Test B
!   Client sends 2 requests to server
!      1st request start server pair pingpong suicide test 
!          request fails due to primary's death
!      continues to retry send request to server until successful reply
!      
!
!   Server primary
!      waits for 1st request, replies and then aborts
!      backup takes over as primary, creates a new backup and aborts
!          on each creation of new backup a count arg is passed and
!          when arg > <TakeoverCountMax> the primary stops aborting and waits for
!          2nd client request and waits to be killed by test shell
!
! Server <TakeoverCountMax> <CurrentTakeoverCount>
!  Primary
!    - starts backup <-(backup take over processing starts here)
!    - mounts device
!    - on takeover count < TakeoverCountMax
!         o accepts connection from client
!         o receives message from client
!         o aborts
!    - on takeover count == TakeoverCountMax
!         o accepts connection from client
!         o receives message from client
!         o waits to be killed
!
!  Backup
!    - opens primary
!    - on a process death notice
!         o takes over as primary
!         o closes primary
!         o startup Primary processing as above
!
! Client
!    - opens Server
!    - loops
!         o sends 1 message to server
!             o expects failures to sends until server pair returns reply
!               which causes loop to terminate
!    - closes server
!    - exits
