bb 1.7.0, top display 139% MEM used

[Joakim Tjernlund]

One of our system ha a strange value in top:
 PID  PPID USER     STAT   VSZ %MEM %CPU COMMAND
 716     1 root     R    42744 139%   0% /bin/snmphndl 

139% for %MEM column is a bit high :)

the snmphndl process has a ton of
3ae94000-3ae9a000 rw-s 00000000 00:07 294921     /SYSV000007c4 (deleted)
3ae9a000-3aea0000 rw-s 00000000 00:07 294921     /SYSV000007c4 (deleted)

3aea6000-3aeac000 rw-s 00000000 00:07 294921     /SYSV000007c4 (deleted)
3aeac000-3aeb2000 rw-s 00000000 00:07 294921     /SYSV000007c4 (deleted)
....

in /proc/716/task/716/maps, I guess this has someting to do with
the 139% figure. Kernel is 2.6.19 on a CRIS CPU:
