[wix-users] MSI logging

I have noticed that specifying + (attach to existing file) option along
with ! (flash each line immediately) option in log file increases
installation time dramatically. (up to 10 times).

Is it bug in MSI engine or it works by design this way?

This is quite critical issue for us - we run several installations
consecutive and want to keep all logging in one place. Also it is important
to have hundred percent match in timing for trouble shouting because !
option writes down actions as they are performed.
