I updated top(1) to show some relevant information for UVM/UBC.

Old memory info:

Memory: 32M Act, 16M Inact, 132K Wired, 504K Free, 3912K Swp, 254M Swp free

New memory info (swap got its own line, Exec = cached executable data,
File = cached file data):

Memory: 32M Act, 16M Inact, 132K Wired, 1920K Exec, 7292K File, 504K Free
Swap: 257M Total, 3908K Used, 254M Free

Any comments? Should I submit it or change something?
