calls than MS-DOS 2.0.

Actually FreeBSD has much more system calls than Linux -- around 540 as
compared to around 300 the last time I looked.
To give a fair perspective -- both UNIX V7 and Plan 9 have around 50 system
calls.
And Windoze 7 has more than 700...

other facilities. plus /proc is an optional
facility. All this conspired to
make /proc less useful in FreeBSD. Unused code is in danger of being
garbage collected in FreeBSD :-)
Whatever happened to the Unix philosophy of everything looking like a
file? Adding more system calls is the Windoze (or perhaps Penguin) way of
doing things.
