Mongotop is measuring more than 1000 ms of work per second.

This is a problem because it makes it look like mongotop is malfunctioning.

Steps to reproduce:

• Run a mongod & mongo & mongotop, all 2.8.0-rc0
• In mongo shell, run the following:

db.testcol.drop()
for (i=1; i<=10000; i++) {
arr = [];
for (j=1; j<=1000; j++) {
doc =

{ _id : (1000 * (i-1) + j), a : i, b : j, c : (1000 * (i-1)+ j)}

;
arr.push(doc)
};
db.testcol.insert(arr);
var x = db.testcol.find(

{ b : 255 }

);
x.next();
var x = db.testcol.find(

{ _id : 1000 * (i-1) + 255 }

);
x.next();
var x = "asdf";
db.testcol.update(

{ a : i, b : 255 }

, { $set :

{ d : x.pad(1000) }

});
print
}

• Give it a minute or two to really slow down.
• Look at mongotop

Expected result:

<1000 ms of activity per second

Actual result:

> 1000 ms of activity per second (by a little)
