Everyone's fav benchmark bonnie

[Mike Tancsa]

It looks like there are a couple of minor bugs in Bonnie with assumptions 
about size that are wrong

e.g.

[releng5-865]# bonnie -s 3000 -d /usr
File '/usr/Bonnie.23191', size: -1149239296
Writing with putc()...^C
[releng5-865]#

Notice the negative value for size
