To try and get better swap space utilization with large programs on my
single RK07, single user system, I would like to change (4.1bsd, in
dmap.h and text.h):

#define	NDMAP 		16	/* size of the swap area map */
#define	DMMAX		1024	/* max block size alloc on drum = .5M byte */
#define	DMTEXT		1024	/* size of blocks of pure text = .5M byte */
#define	NXDAD	12		/* param.h:MAXTSIZ / dmap.h:DMTEXT */

to instead be

#define	NDMAP 		256	/* size of the swap area map */
#define	DMMAX		64	/* max block size alloc on drum = 32K bytes */
#define	DMTEXT		64	/* size of blocks of pure text = 32K bytes */
#define	NXDAD	192		/* param.h:MAXTSIZ / dmap.h:DMTEXT */

Should this work?  Should I have to change anything else, like increase
UPAGES by 4 or 6?  Is this reasonable?
