Re: Mason 1.3 autoflush behaviour change

I suppose we could also change the default to enable_autoflush=>1. I was 
just hoping to make the higher performance option the default, but maybe 
that's silly. static_source is the biggest win and it isn't (can't be) 
the default anyway.

But Jesse, can I ask how you're using autoflush and why several 
well-placed manual $m->flush_buffer calls wouldn't work as well?
