That would help in the cases where I need the log on disk.

As you said in another mail building an in-memory circular log on top of 
boost::circular_buffer should not be too hard, so I'll try.

That is good news - I've found it very useful in tracking down bugs. All it 
lacks is stack trace (which is simply not possible I believe) and a history 
log (that I'm talking about here).

Probably about one line in 4 is an assert (mostly preconditions at the start 
of each function). I'm hoping Thorsten Ottosen's contract programming will 
make it into the standard so the compiler will understand asserts and be 
able to optimize away the redundant ones.

Only if it stays behind the scenes - I like that I define its behaviour once 
in main(); I wouldn't want to have to specify a log name in every 
SMART_ASSERT() line.
