Could be.  You can probably test this fairly simply by globally removing

Not likely, although that may increase the memory used.

There have been patches on the list to flush output periodically, but I
don't think they remove all buffering.  The buffering is what makes
things like filters, wrappers, and exception handling possible.

However, TT is pretty hackable if you want to change that.
