Could someone please enlighten me?  I have been looking through the MINIX
book (I got mine at UNIFORUM :-) source listings.  On page 436, file
h/callnr.h is missing the following system call numbers: 11, 26, 31, 32,
34, 35, 38-40, 44, 45, 49-53, and 55-58.  Is this due to a desire to keep
in line with Version 7 UNIX, or are these 'slots' reserved for future
expansion?  Is there some historical reason for this, or was it just due to
editing, etc?
