<p>If it does, then how do you justify the overheads incurred (journaling etc.)?
If it does not, then how come the pagefile gets fragmented?
Additionally, would increasing the cluster size improve pagefile performance (cluster slack space is a non-issue)?</p>

You can skip the boost namespace entirely by using the techniques described
here
. Just use something like:
```
boost\:\:.*=NoStepInto
```
... in the relevant registry entry.
However if your code gets called from within boost (e.g. through a
```
boost::function
```
or similar) then your code will be skipped as well! I'll be interested if someone can come up with a good solution for
that
problem...
