I'd like to add use case. I think that log messages should be written as soon as possible.
Use case: program crash only on specific machine that you can't debug on. If logs messages will not 
be written immediately they will be lost. In this case this logger is pretty useless. 
I think that if someone prefer to see

> a.cpp:14: result of f()
> [100 lines of other logged messages]
> a.cpp:14: 1234

he should wrote "log viewer" that will handle this.
