Memory mapping files first becomes constrained by the number of
segment registers free.  The hardware for Risc System 6000
has 16, and 6 are already tied
up when your program starts, giving you 10 files which you can map
concurrently.  This is a result of file mapping being tied to the
shmat system call which uses a new segment register.
